So I hear that a large part of why anal fissures don't heal is that you get spasms of the muscles down there - maybe the sphincter?
I'm not sure whether I have spasms. It kind of feels normal after a BM (although when there is pain it's a little tight) but generally I don't "feel" like I'm having a spasm. Would I know about it, or could a spasm be happening even if my anal area is just feeling normal?
