What causes sharp pain in my lower rib cage?
Patient: when I am in a seated position and bend over I get a stabbing sharp pain just below and under my lower left rib cage with my legs crossed in that position it is even worse. When I bend over from a seated position as if to pick up something off the floor on the right hand side of me no pain when I bend over as to pick up something off the floor on the left side of me I get extreme sharp pain..pancreas? YYYY@YYYY Doctor: Thanks for your question on HCM. In my opinion it is muscular pain only as it is associated with movement.  It is aggravated by certain position and movements.  So possibility of musculoskeletal pain is more. Pancreatitis pain is usually  constant and more in the back.So try to follow these steps for better symptomatic relief in muscular pain. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Avoid movements causing pain.4. Take good painkiller and muscle relaxant. 5. Apply warm water pad on affected site.
