Happens to me sometimes and i have ulcerative colitis
Have you found out the problem to your stomach pains? I too have had the same problem but don't know what it is. Due to the fact I no longer have health insurance I figured you might have found out
I also have the same symptoms. I have not eaten anything but yellow corn and lately it has been coming out red and once came out black. I also have had fluctuating stomach pains for about a year.
