What to do if i have been getting really bad headaches for a while now, what could be wrong with me?

See your medical doc: You need to find out the cause and get treated. You may want to check with your dentist for tmd problem.

Bad Headache = Eval: Zouaf, bad headaches can be a symptom of a disease that needs further workup. I would discuss them with your family doctor, and consider seeing a neurologist for further evaluation and treatment. Don't be surprised if an MRI of the brain is recommended because of the change in your headache severity. Evaluation by a dentist is also reasonable if there appears to be an association.
