Anal fissure: What helps it heal?

I've decided to get surgery, it's scheduled for Thursday. Because of a previous surgery many years ago in which the surgeon cut and enlarged my sphincter/anus, the surgeon feels he shouldn't do a traditional fissurectomy and maybe not even stitches. He's going to do Botox + cauterization. What I'm wondering is: What kind of pain, what level of pain, can I expect for the next day or two post surgery? Any feedback would be welcome, thanks!

The sphincter muscle needs to be cut so the fissure can then heal. I have had it done twice.

OMG I know, right?!! I have yet to meet anyone (un)lucky enough to have it enlarged. I was in hospital 5 days, clicking on the morphine as much as they'd let me! Just this local proctologist had this theory and did a few of these surgeries I think. He told me he also had stretched a few assholes (I figure just say what it is!) manually in some way. Ugh. BTW thanks for following along with my 3 replies - appreciated!

Dear Lord. If you haven’t had this issue God bless you you don’t know what you’re missing. Right?? Pain like no other and I have pain all over from my autoimmune diseases.

p.p.s. There's a unique issue with my tushie. Drs enlarged my anus/sphincter in 1983 (it was remarkably painful), so for that reason he just can't cut and do stitches. And maybe even any stitches at all are a bad idea because of that surgery which by the way was maddeningly ineffective.

p.s. Did you get Botox in addition to the cauterization?

Thanks for commenting. I think his plan is to cauterize, but he could change his mind once he's getting a closer look at it. I'll ask him about it.
I hear ya. Sorry you've had less success. bummer.

My fissures have been cauterized and it helped for a very short time. A fiend of mine had her doctor put sutures in her fissure and she never had any more problems. Not my luck mine started in 1990 and I have suffered with them since. Awful.

Okay so I've decided to have surgery after all. I believe this is the best decision for me. Botox + cauterization of the fissure. It's scheduled for next week so I'm looking forward to it/not looking forward to it (if you know what I mean!) Thanks everyone for such great info.

Thanks!
I'm in NJ, so I'm still looking for someone near me.
