I have had unexplainable (frontal) chronic headache with dizziness that NEVER goes away, unresponsive to many various meds including beta blockers. Its very annoying and puts a tremendous damper on my life. I also seem to have non-allergic chronic turbinate swelling.
Is a non-contrasted MRA of the brain and cervical-4-vessels sufficient to rule out any vascular cause, including Basilar artery insufficiency or other problems? I had these scans done and were negative. The MRI with contrast of my brain and without contrast of my cervix spine was also negative.
Things that make me feel better:
Hyper extending my neck and or moving my head around causes a "squishing" sound and temporarily relieves the pain a good bit. Also, oddly enough, holding my nose and blowing air into my ears and holding it temporarily gives 90% relief of symptoms, as does sneezing makes me feel a bit better for a moment.
Question:
Do these negative tests 99% rule out any vascular insufficiency, pathology, entrapped nerves in the neck, and so on?
What else could I be on the lookout for?
Thank you.
