Had to do the final takedown twice after the first j-pouch had to be redone two years into it. Long story but none I'd like to go through a third time.
the one thing that saved my ass (literally) has been and still is ILEX paste. Its like latex on the skin around the "exit" . For me that is the only way to fight the butt burn.
calmoseptine works for a little while but in my humble opinion ILEX gives the most relief.
i order it through Amazon.
good luck !!!
