Migraineurs are often highly responsible, self-sacrificing people with a lot of people depending on them. They are typically bad at relaxation and tend to have cold hands.
We know that migraine tends to run in families. Sometimes a concussion can cause migraine. Stress, diet, menstruation, concussion and other factors can start a migraine or make it worse.
Migraine pain is caused by swollen blood vessels inside the brain pressing against nerves. You can think of migraines as the brain getting stuck in swollen mode. Neural over-activation takes the form of neural vasodilation.
