Hello, I have had a number of ongoing stomach problems. I have severe stomach pain, more so in the lower part, cramping, bloating, severe rectal pain (incapacitating at times), rectal bleeding, and diarrhea. I get this severe pain almost every morning before I even eat or get out of bed. Alot of times this severe pain is followed by diarrhea. I have already had my galbladder removed, and I have been tested for celiacs twice once with a blood test and once with a biopsied sample, both of which were negative.
