I get really bad headaches what should i do?

See medical doctor: Severe headaches can be difficult to diagnose so visiting your medical doctor first is most important. If he can't determine the cause of your serious problem you may have muscle tension pain that needs to be corrected by a dentist.

Evaluation: Meerkat, i would discuss with your family doctor whether referral to a neurologist would be reasonable. A neurologist could help to determine if the headaches were simple tension headaches or migraines, or suggestive of something more serious. As mentioned before, a dental evaluation would be reasonable as well.
