The bicep muscle could be imagined as two muscles side by side that ultimately separate into two “heads” that attach to tendons and connect into the shoulder complex. The short head of the bicep connects to the scapula and is rarely a pain generator. On the other hand, the long head of the bicep attaches to the glenoid, which is where the humerus connects to the shoulder blade, or the area we more often call the rotator cuff. If the tendon that connects the long head of the bicep to the glenoid becomes inflamed due to excessive friction or overloading of the muscle-tendon unit—more accurately described as long head of the biceps tendosynovitis or LHBT—it can be experienced as pain in the anterior (front) of the shoulder.  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏  ͏ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­
