My son had an anal fistula sx removed at 1 yr old. It reoccured ~six mo later but healed by itself. Now, at 5 yrs it's back, isn't healing. Options?

Anal fissure. Maintain a diet high in fibre and use a daily stool softener. There are topical medications that can be used to help with healing. Regular irrigation of the area in the shower to keep the area clean. Review his management with his doctor. All the best and I hope this heals.
