Xiphoidalgia (Xiphodynia) is a syndrome distinguishable by pain and tenderness located in the very distal, lower portion of the sternum
. Lifting heavy objects or trauma to the chest may be the cause of this musculoskeletal disorder and pain may be heightened by bending or twisting. Anesthetic
injections are commonly employed to treat this medical condition. Surgery would be considered as a possibility once local conservative measures fail.
