I've been suffering with a form of dizziness which started quite innocuously but has gradually become very fierce and debilitating. I'd describe it as an intense headrush, like an exaggerated sense of movement, predominantly while I'm moving around, although as it's progressed I've begun to feel it regularly when I'm sitting or lying still as a strong swimming sensation. It's easily visually triggered, so my head will swim whenever I'm working with something directly in front of me; so I find it difficult to read, write, use a smart phone, tablet or P.C, and washing up is an absolute killer. Although the condition has worsened steadily over the last 12 months it has never made me feel unsteady on my feet, but because it's balance related, I experience frequent nausea and on bad days all I can do is sit still and try to move around as little as possible.
I've been seen by various consultants, both ENT and neurological, and although there is general consensus that it's probably vestibular in origin, the exact cause of the symptoms has not been identified.
I've been presecribed Stugeron, Betahistine and Noriptyline, none of which have been effective, but a while ago I noticed that the symptoms were pretty much absent while I was eating. So I started chewing gum, which miraculously gave almost instant relief. Unfortunately my dizziness returns within 30 seconds of stopping chewing, but at least it's given me a means of being at least partially functional during the day.
I'd be very interested to hear from anyone who's either experienced similar symptoms, or who's tried the chewing thing with any success.
