Coracobrachialis pain in the arm is the ache felt at the upper and middle part of the arm. Coracobrachialis is the smallest of the three muscle located at the shoulder joint. Rupture or strain of Coracobrachialis muscle can result in pain in the shoulder's front area and back of the upper arm and forearm. Those who suffer from tenderness and tightness of Coracobrachialis muscle also experience problems with the other muscles that function together with the Coracobrachialis muscle. It is a long and lean muscle at the shoulder joint and is responsible for the function of various arm movements. Overuse of the Coracobrachialis muscle can make it hard and can cause extreme pain while raising the arm and during other arm movements too. There are simple exercises that can provide relief from Coracobrachialis pain in the arm.

Function of Coracobrachialis Muscle

The front portion of the upper arm consists of three muscles – the smallest of the three is known as the Coracobrachialis muscle. This muscle aids in bringing the arm towards the body and also helps in internal rotation of the shoulder. It also helps in stabilizing the shoulder joint when the arm is placed at the body's side. This muscle is named Coracobrachialis muscle as it fastens the coracoid process of the scapula. It protrudes upwards and outwards and is slightly forward from the top of the shoulder blades outside edge. This muscle is not as prominent as the biceps but it has several important functions at the shoulder joint.

The two major functions of coracobrachialis muscle in the shoulder are flexion (bending movement around the joint) and adduction (movement of the arm towards the midline). There are other muscles involved in performing flexion and adduction but the coracobrachialis muscle also plays an important supporting role in these functions.
