This is quite typical for a condition called atopic dermatitis. The most effective over the counter product for this problem would be Hydrocortisone 1% ointment. Apply this twice a day. I would also recommend keeping the area moisturized with Aveeno Eczema cream. Some authorities feel that taking Flax Seed oil by mouth helps, take 1000 mg. twice a day. This would be found in the vitamin area of your pharmacy.
I would be happy to answer further questions.
