I have a pain in my upper abdominal region. its right at the bottom of the rib cage in the middle of my chest. I have been nauceuos the past 3 days and dont feel like eating much at all. I have thrown up about 5 times, but i dont feel "sick" really. i often feel like i have to poop, but when i go to the bathroom, nothing comes out, or just very little. thanks for any clues as to what might be causing this. i guess i will go to the doc tomorrow if things dont get cleared up.
