Has anyone had to deal with pain in the upper abdomen, left side? My doctors are quite mystified. I had a CT scan that showed my Spleen to be normal. The pain has been quite sharp and around for the last month. I can reduce the pain with aspirin, but it is not going away. It wakes me up at night but seems to reduce in the daytime, maybe because I am distracted with work. Any suggestions or thoughts out there would be appreciated.
