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.

The most often prescribed medicines are corticosteroids, which in addition to helping cut down the itching, also promote healing.
