What is biceps tendonitis and strain?
An injury to a muscle or tendon is called a strain. When tendons are inflamed it is called tendonitis. Tendons are connective tissue bands that attach muscles to bones. The biceps muscle is located in the front part of the upper arm. The biceps tendons attach the muscle to the elbow and in two places at the shoulder. When the biceps tendons are inflamed it usually causes pain in the front part of the shoulder or upper arm.
