Had mri and ct. both good. blood work good. getting migraine or tension headaches a lot. throbbing and sensitive feeling. what is this?

What is what?: If you're having migraine and/or tension headaches, then you're having migraine or tension headaches. That's what it is. If that's your true diagnosis, then the MRI, Ct and blood tests were completely unnecessary and a waste of time, resources and needless radiation exposure of your brain. You need to educate yourself about headaches.
