In my opinion there are many people who think that they just have to live with headaches. The majority of headaches (more than 40%) are categorized as tension headaches. I cannot recall a tension headache that has not positively responded to chiropractic / fascial treatment. What chiropractors are doing is reducing the tension wherever we treat.
Most headaches have their origin in the neck / shoulder region. Cervical or upper thoracic manipulation combined with fascial treatment to the surrounding soft tissue always has great effect – often a miraculous effect!
Migraines can be a bit more complicated but most of them can be helped using the same measures. A chiropractor often treats a migraine globally – meaning looking at a wider spectrum to get an effect, such as treating the low back or mid thoracic part of the body.
