I have been having head ache for more than a week and have this high high pitch humming or buzzing it wont go away even went to er and my primary care doctor none of the meds worked.i have been dizzy blurry vision no sleep blood pressure high too?

Further work up will be needed. Ideally a neurologist if you did not have imaging, x-ray/CT/MRI and/or ENT specialist for a detailed exam will be needed timely. The humming is called tinnitus and may become hard to control.

Many possible explanations, but increased intracranial pressure might explain. Have you done a brain imaging study such as CAT scan or MRI? Have you seen a neurologist or scheduled to do so? Do you have history of prior headaches, perhaps even migraines? Can we help point the way via a virtual consult (www.connect@healthtap.com)?
