I've been having this pain in the left side of my abdomen (right below the rib cage) for several days now. I haven't done anything to strain any of the muscles around there to my knowledge, and I doubt that it's a kidney stone because it's lasted this long and I am not writhing in agony in the emergency room.
I really only notice it if I move so that that part of my body has to stretch or squeeze -- probably because of my leg and the brain's gating mechanism for pain. In any case, I am concerned that it might be something else like a problem with my spleen or an infection in my upper digestive tract.
On a pain scale, it's about a four when I feel it. My leg is about a three at rest, and between five and six when I walk (I've gotten used to grading it... it used to be around a seven or eight when I walked).
Anyone have any ideas?
