Had a pain in the backside for nearly 4 weeks now although it did subside for 4 days in the middle. GP initially diagnosed it as piles (which I do have, but it's definitely not them) and then we discussed the possibility of a fissure last week. At first I was on pile treatment and now I'm on GTN cream and lidocaine gel. Nothing seems to help the pain, it's only better in the am after I wake up. Once moving around etc it's back. It's in a very definite place just inside the anus and I'm wondering if in fact it could be a abscess rather than a fissure. Totally miserable with this constant pain, please can anyone offer any advice?
