Bicep tendon rupture
Patients may report experiencing a sudden, sharp pain (and sometimes an audible pop or snap) in the anterior shoulder and upper arm, or they may complain of recurrent pain during activity. Pain may be nondescript or absent, with patients presenting with a palpable "bulge" in the upper arm between the elbow and shoulder. Other symptoms include cramping, bruising, and weakness.
