The biceps brachii is the most well-known of the arm due to its prominence. It is the muscle we think of when we imagine someone with ‘big arms.’ Its chief role is elbow flexion, and, while it is not the only elbow flexor, its role makes it prone to
overload problems which can lead to trigger points. When trigger points form they will produce pain felt in the elbow arm and up into the front of the shoulder. Shoulder pain is usually felt as superficial as opposed to deep in the joint.
