Costochondritis Causes
Costochondritis is an inflammatory process but usually has no definite cause. Repeated minor trauma to the chest wall 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.
Different types of infectious diseases can cause costochondritis.
- Viral: Costochondritis commonly occurs with viral respiratory infections because of the inflammation of costochondral junctions from the viral infection itself, or from straining from coughing.
- Bacterial: Costochondritis may occur after surgery and be caused by bacterial infections.
- Fungal: Fungal infections are rare causes of costochondritis.
