I have had diarrhea for about six days. Today Ihad small red pieces that looked like raw meat but I haven t been eating meat, besides there were a lot of them. I have been to the doctor but these just showed up today. Should I take a sample in for the lab to check? I bloat real bad before I have a movement, and I am getting very run down. The doctor said it would pass but it seems like a long time to me.
