Had nausea and stomach pain for a few days which resulted in diarrhea. now feeling like i have pressure in my rectum constantly. still able to pass stool but generally it is liquid/unformed stool. pressure is still present even after bm?

Your symptoms are consistent with inflammation in the intestine. You may take Imodium for a couple of days. Drink enough water to stay hydrated. If Imodium does not help, it would be prudent to see a doctor. Wish you good health!

If your rectal pressure is quite severe you should have a rectal examination to check for impacted stool in the rectum. When this is present you either cannot pass stool.or only liquid contents can pass around the impacted stool which acts as an incomplete obstruction.
