In addition to your physical examination, your doctor likely will order X-rays and probably an MRI scan. Tears of the subscapularis tendon or instability of the longhead of the biceps in its groove usually require surgery to correct the problem. Complete tears of the pectoralis major tendon or rotator cuff tendon in a relatively young person also require surgery to achieve a satisfactory result.
The type of injury would determine whether physical therapy, rest, modification of your workout routine or surgery would be necessary. I do recommend you get seen quickly by a physician as many of these injuries respond better to early diagnosis and treatment.
