I sometimes get a severe pain/cramp in my upper left abdomen, below my ribs. The pain, like a charlie horse, usually occurs when bending or sitting in an awkward position. Standing up helps the pain decrease, but if i sit or bend again the pain will return. The cramp can last from seconds to minutes. The area will remain sore and tender to the touch for hours or days. I do not note any protrusion. I am morbidly obese, have had various abdominal surgeries. Could this be a hernia?
