i stay away from corn now. because it always gives me looser stools. only eat corn on the cobb like once at a bbq. I am starting to believe that I have a anal fissar. I have the symptoms of that. it said it can release a odorous discharge. although I don't know if that is it because I never wipe any residue from that.
another possibility I found yesterday is that the muscles down there have been weakened by sitting on the toilet to long. I read that can happen. and thus a odor may be leaking out because the muscles are weak. idk I'm sorry for the details, but I'm sure your used to the grossness of this situation. I don't know if this is something you could be dealing with. maybe not if you have already been to a dr. I believe we will find an answer to our problems though. I believe it is something that is right in front of our face and when we find it we will laugh at this whole thing. stay strong. keep looking for answers!
