I get this inquiry a lot and, yes, physical therapy can help! It all depends on the cause. Headaches caused by restrictions in the muscles, nerves and fascia can respond well to physical therapy. For example, when muscles of the jaw, neck and upper back are tight or weak, they can pinch nerves and blood vessels resulting in headache.
For treatment, I use a combination of Dry Needling (IDN), Active Release Technique (ART), and functional exercise. Check out this full article on the CoachAmyPT blog to read more about the effectiveness and qualifications of these treatments for severe or “pop up” headaches.
