Hi, I'm an eighteen year old female. Last Friday, immediately after I woke up and moved, I had a pain in my stomach, right under my Rib Cage. I thought it was a bug but the pain persisted. The pain has been a constant since then. It's been almost a week with it. It seems to be an intense pain under my right rib cage but I do get pain across the middle sometimes. Moving/walking a lot agitates it and sometimes after eating it acts up more. I do occassionally get nauseous but i havent thrown up yet. I thought it might be gas, but I've had normal gas and bow movements. A bit constipated but still normal, everyday. But the pain can get very intense and then sometimes it is like a dull pain and certain positions sometimes alleviates the pressure feeling. Sorry for the long explanation, but any idea what this might be?
