I know Marsh :( :( :(
Unfortunately only one "but" equals one VERY painful "butt"
I really hope you will fix this problem very soon and once and for all.
Just remember - even if you decide to have a LIS - you HAVE to stay on a healthy diet for at least a year since that tissue needs about 8 mos to regain just 80 % of the pre-fissure strength !!! You have to have a long term goal as a motivation
No chicken is worth your pain ; ) - right ; ))) ???!!!
Wishing you fast healing !!!
