Stopped eating high lactose food for 2 wks. still some pain, blood in stool, etc, but i do feel better. no more horrid diarrhea. chronic low-grade fever (7 months) also gone for 5 days now. connected?

Lactose intolerant: Your symptoms may be connected but i would still consider the possibility of irritable bowel disease like crohns or ulcerative colitis.

Depends on history: I see you have had some workup, but not knowing more, i would recommend seeing a physician as soon as possible. Blood in your stool can be serious and life threatening issues need to be ruled out first. Lactose intolerance does not cause bloody stools, but if you have something like inflammatory bowel disease, it could aggravate it. I am sorry I do not have more for you, but see a dr.
