Hi,
I am only 18 months post op and I have tried every ointment and the lidocaine. Nothing ever consistently worked well.
I take 4 Imodium per day. It seems to slow down my transit time enough for the caustic digestive fluids to be reabsorbed before exit.
This greatly helps my situation. I don’t know if it will work for you, but it is my only viable solution for the fire shooting out of my butt 😩.
