I have had tiny small bumps in between, on my fingers and forearms. I scratch them and if and when I do they turn into tiny blisters. Am i allergic to something or are they chilbains. It is some form of excema or dermatitis?
There are several causes of blisters. Since when have you noticed these lesions? It eould be best not to scratch them - this could cause secondary bacterial infection.
'Blisters are usually caused by injury to the skin from heat or from friction, which create a tear between the epidermis—the upper layer of the skin—and the layers beneath.
Short periods of intense rubbing can cause a blister, but any rubbing of the skin at all can cause a blister if it is continued for long enough. Blisters form more easily on moist skin than on dry or soaked skin, and are more common in warm conditions.
Sometimes, the skin can blister when it comes into contact with a cosmetic, detergent, solvent or other chemical; this is known as contact dermatitis. Blisters can also develop as a result of an allergic reaction to an insect bite or sting.
There are also a number of medical conditions that cause blisters. The most common are chickenpox, herpes, impetigo, and a form of eczema called dyshidrosis. '
It would be best to consult a doctor if it does not resolve on its own in a few days.
