Headache for 3 months straight, extreme blurred vision, face going numb and twitching. what could this be? please help.

Get checked: The symptoms without obtaining further history are hard to interpret like that. One i can tell you, get a check up. They are not right and necessitate immediate referral to your doc, unless you've done it already.

See a doctor: Its tough to connect all of those symptoms, but a prolonged headache and blurred vision could indicate a neurological problem like increased brain pressure. I would suggest finding a neurologist very soon.

Couple possibilities: Chronic increased intracranial pressure as from hydrocephalus is potentially serious & could cause such symptoms.Must be checked by dr. Asap! other, more benign causes could come from neck or cranial bone dysfunction, tmj, or other musculoskeletal problems.A good history & phys by your osteopathic dr., incl hands-on exam might be helpful to figure out the cause & manipulation might help treat.
