Yes they were, and they were all negative. But that was 4 years ago. I find it odd that my doctor has never given me a diagnosis and every appointment I have he will not let me even ask a question. He treats me like I am weird for being concerned about this problem. Where I live there are only a couple of gastroenterologist office so there are not a lot of places to turn to. That is why I have an appointment at Mayo in a couple of weeks I need some answers to why I have basically had diarrhea for 4 years.
