Primary headaches occur independently and are not caused by another medical condition. A cascade of events that affect blood vessels and nerves inside and outside the head causes pain signals to be sent to the brain. Brain chemicals called neurotransmitters are involved in creating head pain, as are changes in nerve cell activity.
Primary headache disorders are divided into four main groups:
- Migraine
- Tension-type headache
- Trigeminal autonomic cephalgias (including cluster headache)
- Miscellaneous primary headache
If you have severe headaches it could be a sign of someting more serious, don’t try to “tough it out” see your doctor if they persist.
