Treatment includes medicated creams — that can soothe the itching and stop new outbreaks.Hydro cortisone cream is mostly used.Aloe Vera gel is used to moisturize the lesion.Anti histaminics like loratadine and levocetrizine are the drugs that can be used to relieve itching.

If I receive such a patient in my hospital I also rule out Dermatitis herpetiformis (DH) which is an itchy skin disease that’s characterized by clusters of small blisters and bumps.

The symptoms of DH, including bumps on your elbow improve on removing gluten from diet.Sometimes a drug called dapsone is used to suppress the skin response and improve symptoms.
