Hi, I ve been having severe Psoriasis on my skin ( skull, back, groin, legs, thighs). Have gone through so many different topical creams like Dovobet,Hydroval,Dovonex. It gives healing in rashes and itching for the time being but again resurfaces. It s been almost six years with this problem. Last year, I went through radiations but no progress. Looking for help and advise immediately. Thanks
