The biceps is attached to the arm bones by tough connective tissues called tendons. The tendons that connect the muscle to the shoulder joint in two places are called the proximal biceps tendons. The tendon that attaches the biceps muscle to the forearm bones is called the distal biceps tendon. A pulled biceps results from overstretching and tearing some of the biceps muscle fibers and/or tendons. Pain and sometimes swelling are the usual symptoms. When one of the two biceps tendons in the shoulder is torn away from the bone. Sudden shoulder pain and an odd-shaped bulge in the biceps are symptoms, this is called Proximal biceps tendon rupture.
