Can a pulled pectoral muscle cause pain in shoulder/neck/jaw with pain when I move on right breast? I hve tennis elbow bad as well on same side ofpain

Pectoral Spasm. This can present as pain in the shoulder neck and jaw. However, the heart should also be considered esp is there is history of heart problems. For tennis elbow, i would recommend banding and physical therapy first. Injections can be considered subsequently.
It can. . It can. Keep an eye on it and maybe take some ibuprofen. If it does not resolve or gets worse go see your doctor.
