I have very bad rectal itching it is so bad that it is scard there is leakage constantly, now I have a bad itchy rash on my back ,arms, stmoach, I have used every cream available from the doctors, I have been on prednisone 50mg for 5 days and then 20mg for 5 days, at present I am nystatin/betagerm0.1%/ mupirocin 1:1:1. I also have been taking oatmeal baths as well this has been going on for over 3 weeks. I have also taken antihistamine,allernix,, benadryl ,cetirizine hydrochloride 20mg and now she has me on sinequan . Would the rash on my body be caused by the rectal leaking.
