What’s the difference between a headache and a migraine?

A headache is irritation of the trigeminal nerve network that covers your entire head and face. This includes the base of your skull, back of your head, top of your head, temples, ears (fullness, pressure, pain, ringing), jaws (tightness, from the motor, or muscle innervation of that same nerve), forehead, eyes, sinuses, and teeth. Any or all of those areas can be involved with the trigeminal nerve. That would be called a headache. The most common headache symptom associated wiwith the trigeminal nerve is sinus pressure and/or nose stuffiness.
