I had a chronic anal fissure in 2013. After 6 months of agonizing pain, I had a LIS and in the next day I was cured.
After two years of not being careful with what I ate, one day I had a forced BM and it happened again.
This was 2015. I was devastated. Went to the doctors and applied some lotions. After 2,3 months, doctor said that the anal fissure was cured but it left a small skin there that could cause some pain as well.
He was right, my anus has never been as it was. I've continued to have pain everyday for over a year. Things would improve so little at a time. I bet you know how that is.
I then reached a point where I had months with no pain. But sometimes it still happens. Once I went on a trip and had a hard BM with blood. It hurt a lot like hell for several weeks. Went to see the doctor and he said that if it didn't pass I could have a surgery. I want to avoid that because it's the 2nd time and I don't want to be incontinent, so, as it was healing on it's own I did not chose that.
Now, from time to time, when I have a hard BM, mostly due to my impatience in the bathroom, I have this pain in my anus feeling inflamed and in my leg too (which I find odd). But in 2,3 days it's healed. The problem is that in those days I always feel that that is the time that it's not going to heal and I become frightened and depressed.
I feel that I need closure on this. I think about my BMs everyday in my life. When I'm eating something I start to think: will it hurt tomorrow? Do I need to eat some vegs with this just in case? etc. I feel that it's draining the life out of me.
So I have a question for you guys:
Should I go with surgery? Should I take this for the rest of my life? Is there a cure for this?
Has anyone here has similar issues after a cured anal fissure? What do you do to keep living with a smile on your face even when you know that will happen from time to time? Do you guys have any leg pain like me?
P.S.: I understand that this is not as serious as an active anal fissure but believe me, I know what that is. Twice!

Thanks!
