I have been getting really bad migranes lately they don't stop. whats the diff between migranes & headaches? and what are causes? preventions?

Many - see a doctor: There are many causes and contributing factors that need to be evaluated before someone can tell what the cause may be and therefore what might work for prevention.

Difference: There are several types of headache. Migraine is one of them. Migraine itself has subclassifications. It happens usually more in women. It could be throbbing, involve one side, associated with nausea, vomiting, and photophobia-trouble with light. Warning signs could happen in migraine and called aura.
