The physiological changes in the body during a migraine/headache attack include inflammation, muscle tension, narrowing blood vessels, hormonal changes and more.
People suffering from chronic migraines/headaches mostly turn to pain killers, migraine prevention drugs, and injections in a hope of getting relief from their pain. It is understandable.
The problem with drug treatment for migraines and headaches is that it’s focused on treating the symptoms, not the cause. The relief is a short term solution to reduce the pain but it doesn’t treat the underlining trigger causing the migraines/headaches.
