Hi!
I am a 19 year old male. I have a weird pressing feeling on both sides under the ribcage, usually one at a time but sometimes simultaneously. It is not painful, but it is uncomfortable. It just feels like there is something there pushing against my ribs or skin. It usually goes away or lessens when I am standing up but is more prominent when I am sitting down. The side that I feel it on changes depending on the position i am laying down in or sitting. Recently, my poop has been dark green/black (just today and yesterday). What could it be?
