If the diarrhea continues, you may want to consider a lower endoscopy for further evaluation.
With exposure to radiation in the pelvis, one consideration would be radiation colitis. The diagnosis is normally made via lower endoscopy (i.e. flexible sigmoidoscopy or colonocopy).
If this is the diagnosis, treatment can be medical (including sucralfate or sulfasalazine) or endoscopic (including laser therapy or argon plasma coagulation).
These options can be discussed with your personal physician or gastroenterologist.
Followup with your personal physician is essential.
