I had my appointment with Dr. Poylin yesterday. He said I have an anterior fissure and it is only a matter of time before it opens up again and starts causing more pain.
He gave me 3 options:
1. Do nothing.
2. LIS: 95%++ Success rate; 5% incontinence risk, 10% flatulence incontinence risk.
3. Debridement + Botox: 50% Success Rate; Minimal complications.
I'm leaning towards #3. I can always go back for #2 if it doesn't work.
