Hello,
One possibility for your symptoms is atopic dermatitis. Diagnosed by blood test like RAST. Treatment is by topical steroids or oral therapy of corticosteroids in severe cases and antihistaminics . Topical creams like tacrolimus ointment (Protopic) and pimecrolimus cream (Elidel) are also useful.

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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
