I have chronic pain in my upper left quadrant. it feels sometimes like a pressure or burning, and has lasted for about 5 months. any suggestions?

See a Doctor: You need a comprehensive workup including a history, physical exam to determine where to start investigating. Possible tests to pursue are blood counts, x-rays or ct of the abdomen, possible GI investigation including both upper and lower endoscopy.See a doctor to get this started.

Agree with Dr. M: Your symptoms suggest gastritis and may require endoscopic examination and may be a biopsy.
