I have just returned from the doctors and the blood tests that I had done to eliminate various bowel diseases such as crohns and caeliac disease have come back as being normal. Unfortunately I have bleeding and pain from my back passage. My GP had a look and diagnosed the piles and fissures. I hada sphincterotomy many years ago and we discussed me using fybogel to keep my bowels loose (TMI I know) She has also prescribed some ointment called glycerol trinitrate which is also used in greater quantites to treat angina. I'm not keen on this treatment as it can cause headaches. I explained that I have been having severe headaches but she said that these would be a different type of headache! If the ointment does not work then they will refer me for surgery. I'm not impressed but because of the pain and bleeding will have to give the treatment a try. I would be grateful to hear any positive stories using this ointment for anal fissures and avoiding having to have surgery. I have also heard of botox being used for fissures but that wasn't what was offered I don't fancy that much either. Thank you EJ.
