Third-degree burn or scald. After contact with hot objects, water vapours, the fingertips may become white with a leathery appearance and transient or permanent loss of sensation to touch and pain 4.
In arterial embolism, one or more fingers suddenly become cold, pale or blue, painful, weak, numb or tingly. Cramps may appear and the finger may be hard to move. Contact with the stinging nettle leaves or stems usually causes burning, itchy, red patches (hives, urticaria); numbness may persist for more than 12 hours 7,8.
In sensitive people, contact with poison ivy, oak or sumac can cause allergic reaction with red, burning, itchy and swollen skin; numbness and tingling may persist for several hours 9,10. Deep second-degree burn or scald. After contact with a hot object, liquid or vapours, the affected fingertips are usually red and tender, but can later become more or less numb and remain so for up to a month 11,12.
A minor cut or puncture of the fingertip can result in felon or staphylococcal whitlow — an infection with red, swollen, painful and, eventually, numb fingertip pulp 14,15. Stings of venomous insects, such as a bee, wasp, hornet, spider (black widow, brown recluse spider) and scorpion, can cause burning pain, redness, blisters and swelling in the affected fingertip, followed by tingling and numbness, which may persist for a day or two 16,17,18. Bites of poisonous snakes, such as cobra or rattlesnake, to the arm can cause numbness and tingling in the affected area spreading toward the fingertips 20. In rheumatoid vasculitis (in rheumatoid arthritis and systemic lupus erythematosus or SLE), numbness and pits in the fingertips and red sores around the nails may develop 21,22.
Symptoms of Churg-Strauss syndrome may include difficulty breathing (asthma), and red-bluish and numb fingertips 23. One side effect of certain chemotherapeutics is hand-foot syndrome (acral erythema or palmar-plantar erythrodysesthesia) with numbness, tingling, pain, redness, swelling or flaking of the palms, fingers, soles and toes. Poisoning with elemental (metal) mercury in children: pink, numb or painful fingers, peeling hands and leg cramps (acrodynia) 24.
After an injury, for example, with a hammer, the affected fingertip usually becomes tender and bruised: red, then  swollen and partially numb then dark blue-purple and then yellow-green. Achenbach syndrome (paroxysmal hand hematoma, finger apoplexia) 25 consists of sudden pain, itching, stinging, swelling, coolness, bruising and, sometimes, numbness on the palmar side of one or, rarely, more fingers that last for few days and then resolve spontaneously; this benign condition is due to spontaneous bleeding in the finger. In peripheral cyanosis, fingers and toes, especially nail beds, and, sometimes, the skin around the mouth (circumoral cyanosis), but NOT lips and tongue, become bluish 26.
Cold injuries: hypothermia due to prolonged immersion in cold water or exposure to cold air 27,29, chilblains 28, deep frostbite (persistent cyanosis and numbness after rewarming are bad prognostic signs) 30. Acute artery narrowing due to an embolus (due to atrial fibrillation, thoracic outlet syndrome) or crush injury results in sudden pain, and cool, pale and, later, blue-purple fingers 33. Acrocyanosis — persistent bluish-purple discoloration of the fingertips (and sometimes, hands, feet, knees, nose, lips and nipples). In central cyanosis, hands and feet, especially nail beds, lips, gums and tongue have bluish discoloration, but are not cold (unless the causes of peripheral cyanosis are present) 26.
Sulfhemoglobinemia: overdose of certain drugs (acetanilide, metoclopramide, nitrates, phenacetin, phenazopyridine, sulfasalazine, sulfonamides), ingestion of household cleansers (hydroxylamine sulfate) 26,44. Disseminated intravascular coagulation (DIC), for example, in sepsis (see more causes below under Gangrene). In the fourth-degree frostbite, gangrene (tissue death) can occur, especially after freeze-thaw-refreeze situation 6,13.
Gangrene means tissue death (necrosis); it is caused by blocked circulation, bacterial infection or trauma 48.
Symptoms of dry gangrene: the affected fingertip becomes red, then pale, cold and numb, then brown, purple or black, it shrivels up and eventually fall off  48,51.
Disseminated intravascular coagulation (DIC) due to sepsis, leukemia, malaria, viral gastroenteritis, snake bites, transfusion reactions, recreational drugs, etc.
Treatment of bed bug bites involves two factors namely identifying the insect and treating the infection.
Staying in healthy atmosphere and following healthy lifestyle can prevent you from getting infested from bed bug bites. Eczema is a broad term a for wide variety of skin conditions, but its true synonym is atopic dermatitis meaning that it is found on the top layers of inflamed skin.
Symptoms for eczema include redness due to irritation, swelling (also called edema), ashy texture of the skin as a result of dryness, crusting, flaking, and other symptoms that include itching, blistering, oozing, and bleeding.
As the skin itches, people suffering from atopic dermatitis will be prone to scratching or rubbing, but as this is done, the symptoms flare up further, causing more pain and discomfort. Dry areas will stay as they were prior to receiving sunlight, which will often be most prevalent in joints where the skin touches itself, such as behind the elbows or knees. There is no definitive answer as to what causes eczema, but several correlations have been drawn in families where allergies and asthma are present. To solve this problem for those who find themselves especially troubled by the winter weather the best course of action is to engage in tepid (not too hot, but not cold either) showers, and to dry themselves afterward by blotting the towel on the skin rather than wiping or rubbing it as so many are used to. One thing many should never confuse eczema with is contagious skin conditions, such as ring worm.
Other environmental irritants can include soaps, detergents, and clothing that is harsh on the skin as well as particles from materials. Potential side-effects of using steroid medications include Glaucoma, which is why it should never be applied to the face, especially near the eyes, hypopigmentation, which is when the skin whitens, and another possible side effect is the skin increasing in its severity of atopic dermatitis.
Cortisone creams can work quite effectively, but in some cases they will make matters worse. For those who do not want to treat their dermatitis with a pharmaceutical method, the next alternative is to engage in behaviors that are in support of the skin. For those who work in a wet environment, such as dishwashers and fishermen, it is best to where gloves while working.
Adding to this, environments that are extreme can cause a person to scratch or rub certain areas repeatedly. As extra sensitive areas like the eyes are repeatedly rubbed the result can be a kind of chronic itch in need of being addressed almost constantly. Just as one must engage in self-control over larger parts of his or her environment, so must he or she take control over the need to create relief in this manner.
Not only will it create a more severe edema, flaking, or bleeding, but it may also cause infection as dirt can collect on the hands and under the fingernails that will then be transferred into the the breaking surface of the epidermis. Athletes have been getting in on this trend by taking advantage of new workout technology that wicks away sweat rather than collects it. For those who are unsure as to whether or not they have eczema, it can be difficult since conditions like psoriasis appear to be similar in nature. Patients should do their best to provide the most accurate answers in relation to when the skin irritation first appeared. My name is Kim Wang and this site is my work in progress helping to pass on some of the things my mother has taught me over the years. As they infect certain parts of the body, Lyme disease bacteria can manifest different symptoms at various times. As it grows larger, the rash may take on a bull’s-eye appearance as the center of the rash becomes clear, and while it might become warm, it seldom becomes painful. If the infection is untreated and continues to spread, new symptoms may begin to appear, such as loss of muscle tone on at least side of the face, which is known as Bell’s palsy. In time, more than half of those who have an untreated bacterial infection will begin to experience periodic bouts of arthritis, accompanied by noticeable joint pain and swelling, especially in the knees.


About 5% of those who remain untreated develop chronic complaints related to neurological disorders—including tingling or numbness in the hands and feet, and problems related to their short-term memory and their ability to concentrate.
In the United States, deer ticks are the prime carriers of the bacteria, and since they are brown and quite small, they are virtually impossible to see. The ticks, which are particularly active during the summer months, will attach themselves to an unsuspecting victim and gorge themselves on that person’s blood until they become quite swollen. Since this process may last as long as 48 hours, it is felt that prompt removal of the ticks will obviously help prevent infection.
Failing to wear long pants tucked into your socks and long sleeves, when you know there is the possibility of becoming infected with Lyme disease.
Remember to use a DEET-based insect repellent on your skin if plan to spend some time outdoors. Since its symptoms can be related to many other medical conditions, this illness can be difficult to diagnose. Note that it may take as long as two months after a patient has become infected to detect antibodies with a blood test, and while it may be conclusive, the test does not pinpoint the exact time when exposure to the disease took place.
Enzyme-linked immunosorbent assay (ELISA) – a common, reliable test that is used to detect Lyme disease. Indirect fluorescent antibody (IFA) – another test used for screening Lyme disease antibodies. Western blot test – This is used for detecting the presence of Lyme disease, and in confirming the results of previous ELISA and IFA tests. Most patients can be cured by using antibiotics, especially if they are administered before the disease has actually begun to progress. Generally, cefuroxime axetil, doxycycline, erythromycin, amoxicillin, or another antibiotic is taken orally for a few weeks, and with more severe cases, the medication is administered intravenously. Cefuroxime axetil should not be taken if you are allergic to cephalosporin antibiotics—including cephalexin hydrochloride, cefprozil, or ceflacor—or penicillin.
Doxyclycline should not be taken if you experience nausea, loss of appetite, vomiting or sensitivity to sunlight.
Erythromycin should not be taken if you experience nausea, vomiting, stomach pain, diarrhea or loss of appetite. As a rule, those who are given treatment when the infection has not progressed make a full and speedy recovery, and others also respond well to the antibiotics they are given when the disease is more advanced. Anyone who at risk for contracting Lyme disease is encouraged to become vaccinated before spring arrives. The patient has another condition, such as lupus, ALS, or fibromyalgia, which was misdiagnosed as Lyme disease. Many physicians apparently agree that persistent Lyme disease actually exists, but they also feel that some patients fail to benefit from being treated with intravenous antibiotics indefinitely.
Since then, many insurance companies and doctors have used this report as the basis for rejecting claims and refusing treatment, stating that to do otherwise would be both irresponsible and contra-indicated. Spilling of diluted (1%) phenol (carbolic acid) solution over the skin can initially cause numbness and tingling followed by skin necrosis 61. If it is diffuse and permanent bluish discoloration lasting for more than few days, it’s probably due to impaired blood flow, which is usually caused by atherosclerosis or a clot lodged in the thumb artery. It can often be confused for, or misdiagnosed as, psoriasis and urticaria because they all share similar symptoms.
Lighter skinned people will find that their skin will redden as the symptoms become more severe and darker skinned people will find that their skin color will change as well. Physiologically, the body’s immune system may be overacting to one of many triggers causing the skin to become irritated more easily. They may find their skin flaring up as a result of touching materials that it is sensitive to, such as wool. Following a very hot shower a person with eczema will find that not only is the skin more sensitive, but that the coarseness of a towel further irritates the area, resulting in more cracking and bleeding. Ross Zeltzer notes in his article for Baptist Health Systems about which specific factors increase one’s risk of suffering from it. While some people are more comfortable in a dry environment others thrive in a tropical one.
Those who work in wood shops may find that sawdust is unkind to them just as those who work in metal shops can find the same of steel, aluminum, and various alloys. People who are allergic to pollen or animals may find the reaction come by way of their skin. Most people who suffer from eczema begin doing so before they are toddlers with the vast majority of the rest developing it before they are five years old. Having already covered this area, the next steps are to figure out what steps people can take as a means of not having to deal with it between behavioral and pharmaceutical therapy. But for those who have chronic flare-ups engulfing large areas, or the majority of their skin, Cortisone creams carry risk factors as well.
Along with never using it on one’s face, it should not be applied to the groin, and a doctor should be consulted if it does not work within three weeks. Mild hand soaps like Oil of Olay, Cetaphil, and Dove are highly recommended because they are gentle. These same brands come in body washes as well, but they will not be of much help for those who insist on taking very hot showers.
For those who have something prescribed by a medical professional, use that and to the specific instructions of the provider. For those who have irritated skin that is not eczema, moisturizer can actually be part of the problem, but for those with it, it is vital. However, it is also important to note that excessive sweat causes eczema as well, so for those who wear waterproof hand protection, another method necessary to prevention may be to wear a thin pair of cotton gloves to soak up the sweat that builds up beneath. Cotton and clothes made of a cotton blend are often more gentle than those made of wool or synthetic materials. While sweat is an efficient means of helping the body cool, it is also a productive way to create chaffing. While there will always be stress in a person’s life, there are techniques that can cause a person to settle it to a lessening degree.
After the symptoms of eczema have gone away it is very important to be proactive in one’s self treatment. Sometimes a dermatologist can tell simply by observing common areas of sensitivity like the creases in one’s skin, the chest, and the face. Those who have a personal or family history of eczema, or the common allergies that correlate with it, strengthen the case for a proper diagnosis.
If the area with the irritant is red and inflamed then the culprit has been found, but only if the skin with no applied irritant is not.
A skin lesion biopsy can be taken where a small area is excised for testing, or a Radioallergosorbent Test (RAST) will be performed, which involves taking a sample of blood and mixing it with potential irritants separately.
Also, every patient will not necessarily have all of the symptoms that are attributed to it.
It is found in about 70-80% of all those infected by the bacteria and originates from a tick bite after 3 to 30 days have passed.


In time, some victims develop more EM lesions throughout the body, and they may also show signs of chills, fatigue, fever, swollen lymph nodes, and joint and muscle pain, but there are no other signs of infection. There may also be neck stiffness and severe headaches caused by meningitis, heart palpitations and an irregular heartbeat, pain moving from one joint to another, and shooting pains that cause the victim to lose sleep.
In America, deer ticks are especially prevalent in the Midwest and Northeast, and in Oregon and Washington state, and children who often play outdoors are particularly vulnerable, along with adults who work outdoors on a daily basis.
If you and your physician agree that Lyme disease may be present, the next step will be to do a complete physical examination and bring your medical history up to date. Prior to having the test, you should discuss any concerns you may have with your doctor, such as its risks, what is involved, and what the results may indicate. It should be performed on anyone whose results were equivocal or positive in either of those two tests. Since a PCR test is costly and requires a high degree of technical skill, it is used less frequently than antibody testing. However, some people develop chronic Lyme disease that is resistant to antibiotics, which may be caused by an autoimmune response, hiding the fact that the infection is no longer present. Women who are pregnant or breast-feeding, and children under the age of nine, are usually given penicillin, cefuroxime axetil, or amoxicillin when they contract Lyme disease.
In some cases, the disease will reappear, the systems will persist, and the patient will need additional, lengthy treatment. The vaccine, which has been approved by the Federal Drug Administration (FDA) consists of a three-shot series given at least eight weeks part, and costs about $60 for each injection. After receiving recommended treatment for the bacterial infection, some patients experience the return of symptoms that are both chronic and persistent.
Others consider the Klempner study to be flawed and have continued to treat their chronic Lyme disease patients using established methods and medications. Possible risk factors include smoking, atherosclerosis, Raynaud’s phenomenon, trauma, frostbite, thoracic outlet syndrome, cryoglobulinemia, polycythemia. A person infected with bed bug bites may lead to various types of skin infections and sometimes may even cause blisters. Eradicate the bugs totally from the house using pesticide can help you to overcome bed bug bites.
Those with dry skin due to eczema will find that in the summer months they will not tan evenly. Others may find reactions in certain products like soaps and detergents leading them to have to purchase more expensive, skin-friendly brands that include Dreft and SA8. As mentioned earlier, one may simply contract atopic dermatitis as a result of a mother or father having it. People who work around harsh chemicals may find that the fumes cause their skin to feel irritated even if they are more common chemicals like chlorine or those added to lotions and perfumes.
This being said, a person may still find themselves with dry, flaky, crusting skin behind their elbows and knees, and even on the tops of their heads and the backs of their necks when they are middle aged or retired. The heat, when extreme, will be counter-productive in the process of creating any kind of relief.
Between breathing exercises, physical exertion, talk therapy, and laughing, people who suffer from atopic dermatitis can find relief by forgetting about it temporarily. Regular moisturizing should not stop if it can be helped because managing eczema when it is not flaring up is much easier than when it is, making it true that prevention sometimes can be the best cure. If these areas are red, swollen, itchy, ashy, flaking, or cracked, it may be concluded that it is eczema. This part of the test is very important because it could very well be that the skin was irritated simply from having tape on it for an extended period of time.
While both tests are very effective, they are often unnecessary with proper behavioral care through moisturizing and sometimes applying prescribed medicated creams. If you suspect that you are falling victim to this illness, it is essential for you to contact your physician in order to get a proper diagnosis as quickly as possible.
As a precaution, when you walk through shrubs, leaf litter, or other vegetation, try to stay in the center of the path. In general, the Western blot test is especially helpful when determining if a patient has developed chronic Lyme disease.
In addition, the standards for it have not been fully developed, and false-positive results may be produced in some cases. They often experience arthritis, joint and muscle pain, fatigue, cognitive problems, and sleep disturbance on an ongoing basis. In addition, treatment will be based on any neurological, cardiac and arthritic symptoms that develop in the patient.
If treatment is delayed until the infection is far advanced, even after the infection is cleared, the patient may experience chronic pain, permanent neurological damage, and arthritis. Most adults are provided with 80% protection with this regimen, and to maintain immunization, additional booster shots may be required.
As a result, their standard of living is lowered, and they also they become unable to work, take care of their children, or participate in various activities they used to enjoy.
Klempner, MD et al., claimed that patients with chronic Lyme disease get no benefit from this treatment. So, if it is impaired blood flow, it is not likely you will be able to cure it by yourself by some sort of remedy. It is unknown as to why, but parents who suffer from allergic disorders like hay fever, asthma, and eczema have children who offer suffer from it as well. Those who had suffered from eczema the previous year carried no symptoms while deployed overseas.
As strange as it may sound to some, water can actually be a causal factor in drying out the skin. It creates a thin barrier between the skin and the outside environment that is damaging it, much like lip balm does. This test consists of applying a small area of tape with the suspected irritant on it to be applied to the skin for a day or two.
Another option, a skin-culture test, uses a tissue sample from the patient to study the Lyme disease bacteria, and while it may be accurate, the fact that the results may not come back for several weeks is often looked upon as a drawback.
A few doctors have even reported that their patients experienced a total personality change which resulted in violent, criminal behavior, and that they have even died of the disease. Some say that it is best to apply moisturizer while the skin is wet after a shower and others disagree. Then, the moisturizing barrier will allow the body to soothe itself with its own means before it evaporates from the skin, which will then result in the need to reapply. This cannot be emphasized enough because so much unnecessary and easily avoidable skin damage can be done in the moments after a shower or bath is taken. It is difficult to spot them and hence it can grow and multiply infecting people in the house.
