Sternalis Pain And Trigger Points

The sternalis muscle is not existent in every human. Approximately 5% of us have one. The muscle can send pain from your chest bone area over to your shoulder and into your arm.

Pain Zone

If this muscle of yours contains a trigger point, it is possible that it gives you a painful chest or even radiating pain in your upper inner arm. 

Hence, it might contribute to your arm pain. Here are the instructions on how to relieve upper arm pain.

Attachment Points

When present, the muscle can be located at one or at both sides of your sternum/chest bone. Even its exact attachment points are variable. But generally it is located superficially to the pectoralis major – your big chest muscle – and runs parallel to the chest bone.


There is no particular function that can be attributed to this muscle.

Overuse and Trigger Point Development

As there is no particular function of the muscle, there are no activities that are known to overwork the sternal muscle. But it is known that it may develop trigger points with acute angina pectoris or myocardial infarction.


If you have a sternalis, you may locate it right next to your chest bone - it is running parallel to it -.

Massage the Muscle

I do not have that muscle but I think working on it with a cane or a tennis ball might work pretty well.

I would recommend placing the cane at the top of your chest bone and then slowly working your way downwards. When you hit a trigger point, stop there and massage it with slow and precise strokes.
