For the past year i have been feeling this uncomfortable feeling of something moving down/leaking down inside my anus, and pain all around my lower back, my bum and legs feeling sore, i rush to the restroom but nothing on my underwear, its all internal feeling, i have had a colonoscopy in feb this year, took a stool sample test for parasite and came back negative, i went to a GP surgeon and had a anal fistula and anal abcess surgery done and ive healed pretty good from the procedure, still having this feeling what could this be feel so helpless.
