Sternocleidomastoid Trigger Points and Referred Pain Map #2112761 (License: Personal Use)

The image highlights two primary trigger points in the sternocleidomastoid muscle-one near the mastoid process and another at the clavicular attachment-each radiating distinct referred pain patterns. Red dots indicate common areas of discomfort including the temple, eye, jaw, and occiput, illustrating how cervical myofascial dysfunction can mimic sinus, dental, or neurological conditions. Muscle fibers are depicted with striations to emphasize anatomical orientation and functional tension lines.

Used on physical therapy, chiropractic, or headache management web pages to educate patients about myofascial pain syndromes; supports diagnostic explanation and treatment planning for cervicogenic headaches or TMJ-related symptoms.
