Saw him recently says need scope to rule out ulcer etc but unable to.do it til Dec 1st. I am concerned cuz watery stools are happening even though I am eating brat diet. Now last two days I can't control my bowels and stools have foul smell i can't describe. I was tested for Cdif and results were negative. This is controlling my entire life, any suggestions
