GROSS WARNING!About a year ago, out of nowhere (I was feeling well prior) all of a sudden came an uncontrollable fart. But the worst part is that it was accompanied with this stinky gel. It concerned me that it would start happening on a regular basis & it might happen while out. But it didn't happen again & I'd almost forgotten about it. Then it happened last week & again this morning. It's really scaring me. Not that I think there's something really bad wrong with me, just that I can't be assured of going out in public, no matter how well I feel at the time. Note, this is not mucous, it is gel. What could cause this?
