Bgd,
It's been so interesting following your thread!
It's a shame about the fistula hindering the fissure recovery but from what you describe, the process was treating a very simple and superficial fistula, which should heal well. I had the same experience although my fistula was on the opposite to my fissure and totally unrelated. Fistulas (IMO) are a lot easier to manage and heal well - that exterior groove, where they deroofed it should hopefully start to heal from the bottom upwards and gradually fill in with new skin until it heals up completely. Like you, I had no real pain, just a little discomfort in the early weeks - realistically, it may take a little longer than a month to completely heal (mine was two) but it's not long and I've now no signs that I ever had it - recurrence is very low, so I wouldn't worry too much about that....Hopefully, now it's been discovered you will go on to make a pretty much full recovery as it sounds you're nearly there with the fissure too, which is great!! (That's the more tricky issue of the two) Just keep the wound clean and dry and you'll be fine!! All the best with your continuing recovery...
