Sb2,
After my fissure was declared healed, I still remained in pain so the doctor referred me to pelvic floor physical therapy. The therapist touched my muscles vaginally and said that they were tight so that it what is causing me pain (during and after bm; stinging, hot burning sensations). My pain increases during bm... Then decreases afterwards but it lingers all day long.
I've tried physical therapy but it has not relaxed my muscles now had Botox injected on the pelvic floor... Takes about a week to get its full effect, so I'll see if this helps.
My doctor also said that my muscles are so tight that they could be causing small little cuts around the anus which are not detected on visual examination.
