Last night I had bad pain on the right side of my abdomen, kind of near my back. It was a constant pain which I ranked at about a 7 or 8 out of 10. This happened for like 2.5 hours before I went home. When I got home I used the bathroom (no. 2) and the pain subsided to maybe a 2 or 3 out of 10. This morning it was the same, and I haven't been very hungry yet (I have been busy making food so maybe that's why) and the pain is still slightly there when I press on it. I'm not too worried about it, because I played some hard basketball yesterday and I might just be sore and tweaked something, but does anyone have any idea?
