Hello Thanks for writing to us Left upper quadrant (LUQ) pain has a wide and varied differential diagnosis. This differential is driven by the overlying structures (skin) as well as the internal organs that populate the LUQ of the abdomen. It is important to understand the quality of the pain (constant versus colicky, dull versus sharp) and consider the time course over which the pain developed. The most common diagnoses for LUQ pain relate to intestinal (small/large), splenic, pancreatic, and renal processes. Small bowel causes include obstruction, Crohn’s disease, irritable bowel syndrome (IBS), mesenteric ischemia, and mesenteric adenitis – an inflammatory process of mesenteric lymph nodes that often mimics appendicitis. So I would advise you to check it with your medical practitioner for clear diagnosis. Regards Dr. Tripat Mehta
