After a year...

I am going back to the doctor and want to be prepared at what my options might be. The fisue fully healed twice last year and then retore within weeks. Now I have had chronic pain since August and it is legitimately ruining my life. I have changed my diet, gotten a colonoscopy to cheap for GI issues, I drink a ton of water regularly, etc.

Is it even possible if will heal on its own at this point? If not is just Botox enough if I am close to healing? Tell me everything because once I get there I kind of freeze.
