But loosely speak , most headaches arise due to " referred infliction , " meaning you palpate the pain in a unlike topographic point than where it ’s actually occurring , Dr. Charles Clarke , a brain doctor and worry specialiser at Vanderbilt Health in Tennessee , told Live Science . It ’s similar to how a herniated record in your back can get sciatica , a pain down your leg . For most headaches , an issue somewhere else in the body — like the jaw , shoulders and cervix — do pain in the muscle and nervousness around the brain , he say .

megrim are anothertype of head ache , although technically , headache is just one symptom of the neurological disorder . Migraine worry can be finger in a form of ways and places : cryptic nuisance , surface pain ; the back , left or right of the capitulum ; or behind the eyes .

Migraine pain is more acute than other headache and can be longer lasting . The disorder is often genetic and can cause additional symptoms , such as nausea . The underlying causa of hemicrania are not completely sympathize , but one theory is that the painful sensation is linked to the trigeminal nerve , the sensory nerve for the head and face ; and the dura , the genius ’s protective layer where descent vessels boom and contract .
Pain-sensing nerves send messages to the brain.
One potential explanation for migraine botheration is that an electrical event in the brain stimulates the trigeminal nerve pathways andsets off an inflammatory reaction .

While the relationships between pain around the eubstance and head painful sensation are well established , the mechanisms that cause head ache still are n’t amply understood , Clarke said . But the unspoilt news is that " we are very secure at deal these , " he said . For illustration , life style change , such as practicing yoga ; over the heel counter medicament , such as ibuprofen and aspirin ; and prescription medicine for more severe headache disorder can go a recollective way to reduce worry severity and relative frequency .
" If people need help [ with concern ] we can often make them a band salutary , " Clarke said .
