The coracobrachialis muscle can trigger pain at the front of your shoulder as well as at 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 its synergists.
Those are the pectoralis major, the front part of the deltoid and the short head of the biceps brachii.
If your coracobrachialis harbors 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 trigger 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.
