It's so wonderful that you are not having any pain! I'm sure that means good healing going on. I think you're right that the tissue will be tender for a good while - people here say up to a year or even two (yikes!). You are very brave trying alcohol and onions - wow. I couldn't even think about that. You might be having some mild IBS/food intolerance. I think that's what I have. It might be just getting older, or we could have just triggered upsets with pain, anxiety and changes in diet ... or it could be age

(was it Bette Davis who said 'getting old isn't for sissies'?) Have you tried probiotics?
I'm still struggling a bit with digestive issues too. I couldn't think about taking Miralax since my BMs are almost always loose. I'm actually in a bit of a catch-22 situation: solid stool makes me feel like I'm being split in two (anything near a diameter of a quarter and I'm in serious pain); yet, loose/water stool burns like hell

I think that my problem may be more than just the fissure. I can see red, raw tissue that isn't where the fissure is - it sometimes bleeds from other places as well :(
I'm not sure what I'll do if surgery is not an option for me, or if the surgery doesn't work. I'll find out on May 10 what my fate is ... but truthfully, I would love to be where you are now. Not to belittle your current struggles, because I know it can't be much fun for you even now. But I would love to be on the road to healing instead of in this limbo land of burning and bleeding and dreading BMs!
I'm so happy for you that you are moving forward with no pain - I'm going to do my best to be where you are very soon.
:D
