Need to see doctor .Will ask about any family history with eczema .Apply moisturizer to affected area dont let it dry out it can be very painfull or just look alfull and some times it goes away with age

Best medicine for the job is Betamethazone. Ask your doctor about it. It's by prescription. It's a cream, doesn't hurt. And it should get rid of the exzema in a week or two.

Mostly eczema. Skin diseases as a rule do not go away in a hurry. So be prepared for a long haul. The disease is only an irritant so no need to panic
