Hello.i started these symptoms 2 months ago suddenly out of the blue after several bowel movements.i feel the need to urinate frequently after a bowel movement.i saw several docs and had a rubber band ligation for hemorrhoids and have a small anal fissure under treatment now. The frequent urination sensation is triggered by the bowel movement.several docs told me its a muscular thing between the bladder and colon and is spasming when passing stools or its hypertonic or pelvic floor dysfunction.i have twitches and spasms in my perineum too.i appreciate the feedback.
