What causes costochondritis?
Costochondritis is an inflammatory process but usually has no definite cause. Repeated minor trauma to the chest wall, overuse of the arms, or viral respiratory infections can commonly cause chest pain due to costochondritis. Occasionally, costochondritis as a result of bacterial infections can occur in people who use IV drugs or who have had surgery to their upper chest. After surgery, the cartilage can become more prone to infection, because of reduced blood flow in the region that has been operated on.
