So, here's my story.
About eight weeks ago, I was diagnosed with labyrinthitis. I has a feeling of motion sickness, which over the next few days began to acquire vision problems. About a week before this, I manifested TMJ/TMD symptoms (pain on the left side of my head and jaw) following getting my neck snapped at the chiropractor. So I'm unsure whether my subsequent problems are viral, mechanical, or something else.
To make a long story short, after going off the cerc four weeks ago, I began to experience blurry vision in my right eye when I wore my contact lenses. It is not present when I wear glasses - but there is minor fuzziness in both eyes peripherally and minor spotty/grainy vision (floaters sometimes) when looking at a clear field, like the sky.
The situation with the contact lenses has improved - sometimes I can go an hour or more with perfect vision in both eyes when wearing contact lenses - even better than when wearing glasses. BUT, and this is a big but, I now almost invariably get vertigo for two hours or more after switching from contact lenses to glasses.
Associated symptoms include bouts of nausea, transitory head pain on the back, top, or side of my head, or around my left temple/sinus.
I had a CT scan which showed nothing of concern, and an xray of my cervical spine, which showed slight compression. I just got an xray of my sinuses but don't know the results yet. The doc felt behind my ears, and couldn't feel anything "labyrinthitic." He's referred me to an ENT and neuro-ophthalmologist. Naturally, I'm freaking out.
