How can i treat my dyshidrosis eczema that only hits me in summer every year. ?

Itchy finger bumps: Dyshidrotic eczema is a very itchy rash of little bumps on the fingers or hands, and may occur on the feet. The bumps may have some fluid inside, but don't break open (unless one scratches harshly) like chicken pox or herpes sores. Dyshidrosis is usually treated with prescription cortisone cream for 1-2 weeks, plus moisturizers like CeraVe. Hydrocortisone 1% may or may not be strong enough.
