Interesting observation

First of all, I have had a fecal odor emitting from my anus for the past 2.5 years. I've tried just about everything that you can think of to make it better. The latest thing that is helping some but not completely is flax oil which I take 4 gelcaps a day. Seems to help bulk up my stool.
I suffered a back injury recently that left me on my back on the couch for about a week straight. During that time I was taking pain medication (lortab) and muscle relaxers just to be able to make it through the day because the pain was so bad. I normally don't like to take meds like that. I did notice during that time that my stool was much more solid and compact. In fact it usually felt like it was so bulky that I couldn't pass it but I always did. I think the smell was not as bad during that time and it seems to me that the change in my stool had something to do with it like maybe it was cleaning out or scraping my intestine better since it was so bulky.
I noticed this same thing when I had surgery for a hernia a few years ago, the bulky stool. I just wish there was something I could naturally to keep my stool that bulky and not have to drink tons of stuff throughout the day.
