Last summer I developed its red hands and inside fingers blisters . Once they pop from scratching so much they really become itchy and raw. This summer it started up again. Went through the cycle with hands? It went to my right arm in the crease of elbow. Got a steroid shot. Thought it was going away? Now it's on both arms! Ugg!!!!!
Hello,
I cannot confirm anything without examination but it can be contact dermatitis, allergic reaction, folliculitis, sweat dermatitis or heat rash. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
