Sever left side pain around rib cage for about a week constant ongoing never ending very sharp shooting and staving pain?

Need Work Up: Severe left-sided pain around the rib cage could indicate a problem in any of the following areas: stomach and gas, cardiac, lung-related, musculoskeletal, intestinal, pancreas and less likely spleen. Given the constant and unremitting nature of your pain, I would suggest an urgent evaluation, possibly with ultrasound and routine bloodwork to start.

See PCP for EKG: Sounds like muscular spasm or costochondritis. But anytime there is ongoing chest pain, a cardiac (heart) must be done. Costochondritis is inflammation between ribs and sternum. It is usually treated with anti inflammatory meds. Strains are treated with rest,ice, and anti inflammatory meds.
