For most people headaches are straightforward and normally pass fairly quickly. However, in some cases symptoms may be persistent.
Your osteopath will be able to assess your headache and identify if it is caused by your musculoskeletal system (e.g. due to a problem with your jaw or perhaps your neck joints or muscles) or something else. They will be able to decide how best to manage your problem and if it is necessary for you to see your doctor.
