Hello, I am 5 days post op and am looking for answers and adding a little advice. I did not use the spirometer like I shoul have and got a touch of pneumonia. USE IT. I got on anitbiotics yesterday and the fever is finally gone. I had to drink contrast dye yesterday and thought I would not get through it. I did but was unable to drink my fluids like I should have the rest of the day. I feel better today but the biggest problem I have is diarrhea. Every time I take an oz. of fluid my stomach grumbles and off to the toilet I go. I am just curious if anyone else is experiencing diarrhea or should I strike this up to the contrast dye and hope once my body gets rid of it I will feel better.
