Hello,
It can be due to environmental allergies that you are having this itching. Diagnosis of skin allergies includes Skin ***** tests (pricking the skin with a needle or pin containing a small amount of the allergen ('***** Testing' or 'Scratch Testing'), Patch tests (by applying a patch to the skin, where the patch contains the allergen.)And RAST.

Treatment includes avoidance of the allergen, oral antihistaminics; topical application of corticosteroids. You may try application of calamine on the affected site. It may work by soothing the skin.

Please seek an appointment with a dermatologist for your complete examination and for figuring out the allergen to which you have allergy. 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.
