The coracobrachialis muscle is able to give you pain at the front of your shoulder and the back of your upper arm and forearm.
People that suffer from tightness, tender or trigger points in this muscle, usually also have problems with muscles that act with it synergistically/together.
Those are the pectoralis major, the front part of the deltoid and the short head of the biceps brachii.
When your coracobrachialis contains trigger points, it can give you pain right at their location and send it to other, seemingly unrelated areas of your body.
In the pictures you can see that trigger points in the coracobrachialis can create pain that radiates down the backside of your arm to the back of your hand.
It might also be possible that you feel an ache at the side of your shoulder.
Less often the back of your shoulder will be painful.
It can be involved in the following symptoms.
The intensity of the colour indicates how common pain is experienced in those areas if trigger points are present.
The darker the red, the more common the pain is.
