I have pressure in my rectum.  It comes and goes, I have had colonoscopy 17months ago everything was normal.I have had diarea off and on for several months now.  Just started taking psylium the last several days it has helped, but today unbearable pressure and pain.  Cant feel any hemrroids, not painful when I try to see or feel.  What should I do it is the weekend.  I did make a appt. with GI Dr. would he be the right one or a specialist in this area?  Please help!
Hi and welcome to Chat Doctor. You should consult proctologist. The most anorectal disore Chat Doctor.  Some more serious diagnosis such as cancer, Crohn and ulcerative colitis should always be ruled out. Your problem can be caused by hard stool as well. You should try to take some laxatives to see will it be better. Specialist should do examinations, at least rectos copy and digitorectal exam. There can be some organic lesion, but also he can find weakness of anal sphincters. If you see blood in stool, have obstipation for more than 2 days or abdominal distension you should go to emergency department. Wish you good health.
