There are many causes of migraine headaches, from diet, stress, hormonal changes, light changes and so on. Tension in the neck musculature can be a contributing factor in some migraines, with reduced blood flow in the vertebral arteries, and reaction in the blood flow in the brain. An assessment of the whole spine to establish any imbalances that might lead to increased muscular tension at the back of the head, can help.  Osteopathy can treat the spine, reducing muscle tension at the base of the skull, improve mobility of the cervical and thoracic spine, in particular. Personalised stretch exercises will help maintain the movement and keep the muscle tension to a minimum.
