What differentiates a migraine from a regular headache?

Severity. Migraines can be on one side or all over. They are less frequent than tension headaches, but more severe. They happen about once a month. Some people have an aura before a migraine (flashing lights or blind spot). Migraines frequently come with vomiting. Bright lights and noise usually make migraines worse. Lying down and sleeping often relieve the pain. They may occur in other family members.
DISABILITY. Migraine headaches (migraines) tend to make people disabled: meaning patients are unable to function in their daily routine due to pain. Migraines tend to be throbbing, 1 sided, causing nausea, and/or vomiting. Both kinds of headaches may respond to tylenol (acetaminophen) (acetominophen) or Aleve (naproxen) but migraines may need stronger analgesics (pain meds). Migraines tend to 'run in families'.
