For about 5 years, I have suffered dizziness on and off. It was last triggered (after 6+ months of being 100% fine) when I had a cold and blocked nose.
It's gradually started up again. I would describe the symptoms as sudden bouts of dizziness (a sort of whooshing head feeling) which also seems to affect my sight in terms of depth perception. It's hard to explain but sometimes it feels as though things are a lot closer than they actually are and my focus seems to shift. I occasionally, at it's worst, feel travel sick, and sometimes I get the feeling that I am going to fall although I don't.
I've not felt so dizzy that I needed to sit down since my first bout, 5 years ago. At which point my doctor looked in my ears and said they were red and inflamed.
I've been to see a specialist and as it had died off at that point, they really weren't able to be much help.
It's driving me mad and I just wish I could get rid of it. Any help would be greatly appreciated!
I have had patients describe dizziness that seems connected to sinus pressure and problems, but you might investigate the possibility of BPPV (benign paroxysmal positional vertigo). BPPV is not otherwise dangerous, except that vertigo results from particles floating in the canals of the inner ear (vestibular portion). BPPV is characterized by sudden bouts (which may be brief, 15-60 seconds) following particular head movements or positions. Vision is often disturbed, as the eyes are reflexively trying to drift (the eye movement due to inner ear stimulation is called "nystagmus"). Some describe their nystagmus as the world spinning, but also as "blurred" or difficulty keeping focus. BPPV can be quite mild in symptoms to very powerfully severe.
BPPV is fairly easy to diagnose when active by simply moving you through various positions while watching and/or recording the eye movement via infrared camera (or electrodes) in the dark (so you cannot fixate your eyes on an object and suppress the movement). This type of testing is most often performed by Audiologists or Physical Therapists, although sometimes technicians do perform under physician supervision. You should search for clinics in your area that perform vestibular/balance testing and treatment.
Speaking of treatment, BPPV is most often treated by repositioning therapy (taking head through deliberate movements to direct particles out of the affected canal (you have 6 total canals, 3 on each side oriented in 90 degree planes of each other). Usually 2-3 sessions are all that is needed for most cases. Medications are not very effective and only treat the symptoms not the cause.
Hope this helps and feel free to post what you find out.
