Hi. I ve experienced vertigo and dizziness off and on for almost 3 years. I ve had 2 bad episodes of vertigo where I couldn t walk straight. The last one was about 2 months ago and I ve been dizzy to some degree since the, ranging from dizzy all day to dizzy randomly throughout the day. I m not very dizzy with my head straight. I also have pressure at temples, forehead and cheeks. And a contant headache, ranging from moderate to moderate plus. Sudafed and Alieve help but do not makes the symptoms go away. Audio test reveal normal hearing loss for my age. Dizzy test results do not indicate inner ear problems. The ear, nose and throat Dr has ordered an MRI. My husband thinks it is sinus problems. I have very little nasal discharge and no drainage down throat. What do you think?
