Dear Dr. In 2005, I Suffered From Skin Allergy Over

Dear Dr. In 2005, i suffered from skin allergy over a month that was cured by "Siva immuino drop" under the direction of a skin physician.After two years, again the problem was repeated, but re-cured by same drug.In 2012, again the same skin problem repeated but , Siva drop didn't work.The same doctor prescribed various anti allergic medicines like :Ebastin, Montair LC etc, but response was nil.Homeopathic treatment also didn't worked .Now-a-days i am applying some Ayurveda oil the gives temporary relief.Today some other physician has recommended Clotrimazole dusting powder with trade name Panderm.Since problem is repeating, please suggest what should i do.
