Hi Karilann, I introduced myself on the Welcome New Members thread. I was diagnosed with PPMS 10/05 then undiagnosed earlier this year. Apparently I'm now suffering from Nobody Knows What You Have. Although I changed neuros after I was undiagnosed and current neuro thinks definitely MS but we have to wait for evidence.
But - I definitely experience something similar to what you do. I feel "tippy" even sitting in a chair. If I move my eyes too quickly I get a weird feeling similar I think to what you're describing. My head feels "foggy", not brain fog but just not right. I'll stop now because I am sounding so vague!
I know there are anti-vertigo medications out there, I don't know whether something like that might help? I can't really help but I can definitely relate!!
