I have been in practice for 30 years and my experience with headache patients is extensive. Many migraine suffers as well as tension headaches not to mention other causes have been solved with chiropractic adjustments and exercises.
So often a headache will start in the cervical [neck] or upper thoracic [shoulder region and upper back]. The cause is very often a subluxation and muscle contraction. These issues will cause nerve irritation and thus pain over the suboccipital [back of skull] region which can radiate over the head and even over an eye. Many patients also get ear and eye problems with this headache.
I utilize a surface emg to measure the nerve and muscle irritation as well as a computerized posture scan. Many times specific chiropractic adjustments along with postural corrective exercises solve the problem.
