So I've had stringy things in my stool for about a year now.I saw 3 different doctors for it. I saw a gastrologist, an ultra sound technician, and I had surgery so that they could look inside of my stomach. All three doctors told me that there was nothing. Even in my stool sample. But it's so clear and easy to see in my stool. Should I be concerned? What should I do?I can't afford to see anymore doctors, just for them to tell me nothing is wrong.
