Examinations of 31 patients with self-reported sinus headaches and 30 patients without a history of headaches revealed that neck pain and cervical musculoskeletal dysfunction were common among those with sinus headaches and may be a contributing factor to headaches attributed to sinusitis. The researchers recommend further studies to understand these associations. Chiropractors often treat patients with sinus headaches and accompanying neck pain/dysfunction with a combination of lifestyle advice, manual therapies, and nutrition counseling.
