Hi! I recently have been experiencing pain in the upper left hand side of the abdomen, below the left rib cage for about three weeks. The pain feels like a sore muscle pain (similiar to pain one experiences from lifting something too heavy) and then I feel the pain in my left rib cage and shortly thereafter the pain goes into my back into the middle section of the back. I saw the doctor and he first suspected gastritis. However, the test results came back normal and the h. pylori test was negative. In addition, food does not aggravate the pain. I can sleep throughout the night but during the waking hours the pain is there. The pain arrives suddenly and then can last for hours or for days. There are some days when the pain is not there and I feel like my old self- healthy and happy. I would appreciate it if someone would answer my question.
