Pain in left side of chest.

Get eval: Without any other information and just a statement saying "pain in Left side of chest" my only recourse is telling you to get an evaluation ASAP, to assure it is not your heart.

It depends...: There are many potential causes of chest pain, from musculoskeletal to respiratory to cardiac/heart, among others. Without a complete history & exam, it's impossible to determine the cause of your chest pain. You should make an appointment w/ your primary physician to determine what testing or treatment is needed. IF IT'S NEW CHEST PAIN WITH EXERTION, YOU SHOULD GO TO THE CLOSEST ER IMMEDIATELY

Multiple: Costochondritis, inflammation of the lining of the lung, heart issue, rib pain, ligament issues, referred pain from neck, indigestion, kidney pain, spleen issues.

To ER for chest pain: Need to head to the emergency room as fact as possible, especially if also shortness of breath, the pain is like a pressure, radiation to jaw or left arm, sweating, vomiting. Cardiac until proven otherwise.
