emf4048, Yes, the diltiazem is similar to the nitro. The nitro did'nt help for me, plus I got some headaches from it. The first doc I saw though was'nt a colorectal surgeon and was'nt sure how to use it. Like I said I did'nt have alot of pain just irritation so it was hard to tell if it was working. The colorectal surgeon said she could see it from just looking even without a scope. It seems like alot of people who have had hem. surgery developed fissures after. The hem. surgery is one surgery I wish I would have never gotten. I still sometimes get a weird feeling there, not really pain it's hard to describe. I also have skin tags that I did'nt have before the surgery. It is been 4 months of hell for me. I was and am still afraid the fissure is still there or will come back and I will have to endure another horrible surgery. It has been a nightmare. I took stool softeners, increased my fiber, took vitiman c, fish oil and any other healing agent I could get my hands on, but I think prayer helped me the most. Alot of warm baths seemed to help too. I really did'nt need pain pills. My colorectal surgeon thinks the soreness I'm having is just from where my surgery was(4 1/2 months ago!!!!) Were your hemorrhoids real bad before surgery? Mine was not, but I had a surgeon tell me he'll could just cut it off and that would be it, BIG mistake.I hope I can help you, let me know if you have any more questions!Try to relax, that will help!
