Before I had trouble with urinary and had to use catheters. Now, I have been having diarrhea for months. I went to one gastroenterologist and he wanted three samples, dashing back a couple more times to do my three samples. I don't have a car so I couldn't do all that dashing and that would have been way too expensive to use cabs for all that dashing. Recently, I went to another gastroenterologist and he only wanted blood work and one stool sample. That may sound simple. I had the same trouble with trying to urinate in the cup. I poop everywhere, but then when I try to get a stool sample, nothing happens. Another very frustrating situation. Finally, I was able to get a stool sample to drop off at the Lab. Has anybody else had this trouble?
