Upper chest pains located at the level of breast bone (central chest area) like stabbing, sharp pains that get worse with movements of upper torso, are characteristic for costochondritis.
It is an inflammation of the cartilage that joins the ribs to the chest bone.
Pain can be felt on the left or right side of the chest, or like upper chest pains, burning pain when touching the ribs, will increases with activity, exertion, or deep breathing and will decreases with rest, or slow breathing.
This pain tends to wax and wane, some days it will be worse, while other days it will be much better.
Costochondritis is usually associated with secondary symptoms like rapid, irregular heart rate and shortness of breath or difficulty breathing.
This inflammation can appear as a part of other systemic inflammatory diseases including fibromyalgia, psoriatic arthritis, ankylosing spondylitis, reactive arthritis, and inflammatory bowel disease (ulcerative colitis and Crohn's disease).
It can result from a chest trauma or exercise-related injury, too.
