Not sure what it is, but this pain has been on and off and very settle for months now. It is on the left side of my back, just below the rib cage there is a slight pain. Seems it happens about 20-30 minutes before I need to go to the bathroom (poo). I seem fine aside from these pains, I am not losing any weight, I am active, etc. My hair though seems to be prematurely balding considering i'm only 22. So i'm wondering if I should actually take the time to go get this pain checked out, its been ongoing for months and months now. Not a big issue really, just a slight pain here and there under the left side of my rib cage on my back. Blood in stool? Not sure how to check really, sometimes my stool is orange/red in color but i'm not sure if its blood or if its just what i've eaten in the previous days.
