It’s almost like trying to walk on a boat passing through a storm, everything feels like it is moving.
When I turn my head to the left while lying on my back a rapid horizontal nystagmus is triggered and if it is positional like that then that would suggest something “mechanical” (like a calcium crystal in the inner ear canal breaking loose and moving around) but that would not explain why I have a difficult time tracking with my eyes when (for example) trying to read from left to right.
Balance is achieved through a combination of vision (it looks like I am upright), vestibular function (it feels like I am upright) and proprioception (the floor feels level against my feet).
I will be trying to get some sort of blogging routine going again but for a while it’s going to be a lot of short posts just trying to catch everyone up on the stuff I have not written or talked about.
