bgd, though I didn't go through all of your diary, skipped through the posts, it really was a great read! Hope you are doing well now. I laughed hard when I read about your confusion regarding long pain episodes even though the fissure is only 1 mm!
A month ago, I was in such a pain that I swear I felt there was much more wrong down there - like a tumor or something - that is going to kill me dead. Because there was NO WAY i could be in so much pain from something that was not going to knock me dead. There were days I could barely walk to my bed after coming out of the restroom. Two weeks ago when I visited my CRS, i was surprised AS HELL when she said "Hey it is so damn small, only a .5 mm probably". Considering the pain, I expected she would say OH GOD THAT IS ONE BIG GIANT WOUND. Lol. Anyway, fast forward to today, I spent two weeks passing bristol scale 4 stools and it was as if the fissure has absolutely vanished. Until i had to strain on the toilet 3 days ago and things have slightly aggravated a bit. Hope you are feeling better!
