What is the difference between a migraine and a headache?
The difference between a migraine headache and a tension headache is that while a tension headache involves the muscles and fascia of the scalp and neck tightening and causing pain, a migraine involves a large chemical change that affects the entire body. Blood vessels in the brain become wider, serotonin is lowered, and nerves misfire – causing severe pain – along with a host of other symptoms like those mentioned above that usually do not occur in non-migraine headaches.
