Hi Doc, I have noticed a fishy/ foul smell during almost every BM. Sometimes, it smelt of coffee. It is very noticeable and embarrassing at times... I have gone to the ED a few times due to colitis or an illius and recovered, but never tested for anything specific. Form of it varies; it s lime green and frothy almost every time (possibly from a cholesectomy), dark/ brown and starts out formed and is really soft. I have read that it could be an infection. I m on amoxicillin for a root canal Q3d for 30 days. Will that help if I do have an infection? Please let me know your thoughts. Any advice or points to bring up up to my doc will help. Thanks in advance! Best, Berna
