Costcondritis can stem from injury/trauma, infection, off alignment of the rib cage...there is almost always a root cause and the underlyinfg cause should be treated....http://www.mdjunction.com/forums/costochondritis-discussions/general-support/1228619
this is inflammation of the cartilage that connects the inner end of each rib with the breastbone (sternum). it can be more painful during exercise and cause chest tightness, massagage and anti-inflammitory drugs will help. good luck
