Re: Leaking mucus when passing gas?
I don't have any experience with what you're going through, but it could possibly be from infection, extreme activity (such as from IBS), reaction to the assult in that area producing more mucus, dysfunction of the sphincter...etc.
How are your bms at this time?
Did your doc suggest any fibre supplements or even probiotics?
How about any rectal meds or even antispasmodics that could help?
Is there such thing as therapy for the rectum...after you heal...such as kegel exercises?
It's all a matter of perspective!
