Sequoia - I have just had my 6 week check up and I do have a fissure! Argh!! Just what I needed. I have been given some cream for it. Does it help? How is yours now?
What cream are you using? Rectogesic was the only thing that helped me but it's hard to combine with BF'ing. Mine wasn't treated til DS started sleeping through at 7 weeks, so I would feed him, apply cream, hope like hell the headaches associated with it wouldn't start before I fell asleep, and it would be out of my system by his first feed in the morning.

summerluven started a thread which I tried to find for you called - Anal Fissure, Lovely Dinenrtime Conversation Topic! That was a most helpful thread and lots of good suggestions in there too.

Good luck.
