The SCM refers to the sternocleiodomastoid muscle. This muscle run along the side of the neck to the front and middle of the chest. This muscle is often the cause of whiplash symptoms following a car accident or other high-impact jolt to the head or body. When this muscle is massaged it can alleviate incident-related headaches because this muscle holds several nerve-triggering points that may cause headache pain.
An SCM massage is often considered when patients are seeking natural remedies for headaches or headaches following a car accident.
