Hey william, I think the same thing is happening to me, I feel it's the fissure site bothering me, I have burning and what feels like inflammation after BM, but according to my GP it's just nerve pain as they are knitting back together which could take who knows how long?!?
I guess it's a long road to recovery which I'm travelling, my destination being "Healed" sometime in the near future!
Keep in touch ~ Steve
