Most of us understand that skin problems can bring about unwanted attention. For that reason, and because this dermatitis presents itself with tiny blisters and intense itching, this article may be the comprehensive overview for you.
The pinhead size blisters usually are on the soles of the feet and palms of the hands, especially on the inside of toes and fingers. If the eczema has been present for a long time, the number of blisters increases forming larger blisters as the small ones merge.
Scratching can lead to irritation, redness, and sometimes cracking and bleeding. It seems as though the primary concern of the physician is to stop the itching. By stopping the itching the area is not scratched and inflamed so much, thus avoiding cracking the skin which can lead to open areas exposed to infection.
The most often prescribed medicines are corticosteroids, which in addition to helping cut down the itching, also promote healing.

There is a particular type of eczema that affects millions of people worldwide. It is called dyshidrotic eczema, or dyshidrosis. I have written an article about it because I am affected by it.
The salient characteristic of this eczema is tiny blisters, tapioca-like that occur between the fingers and toes. If the condition worsens the blisters can spread to the bottom of the feet and the palms. If it gets worse and is not treated, the blisters can get larger until adjacent blisters become larger blisters. Eventually, there is the possibility that there is cracking of the skin (usually due to excessive scratching), bleeding, and crusting.
There are definite steps to treating this eczema which physicians can deal with rather quickly. If remedial steps do not improve the condition, you need to see a doctor. You may need a strength of corticosteroid cream which can only be prescribed by a physician.
