I have a fissure by my rectum that is causing much discomfort. I had it many years ago and was prescribed a lotion that would turn into a powder after application. It worked well after a short period of time. Now, once again it has reared its ugly head and having to deal with it. I can't remember the name of the medication and was wondering if you could identify? Need name of medication for fissures. A lotion that turns into a powder after application?
