This comment is soooo... after the fact, but I too have been battling inconsistent imbalance , weird spacey head feelings that medical personnel call "dizziness", tiredness sometimes not long into my day depending what I'm doing, where my coordination decreases to the point of dropping stuff , just being clumsy in ways that are unlike me. If I'm feeling that way I find if I take a nap of about an hour and a half , I'm better after. After going to neurologists , ENT's etc, I ended up with a PT who was trained in "Vestibular" issues, not your typical ones , but the more involved ones. I will share she treated me for Vestibular Migraine. It did help. But that was a few years ago and I actually came to this site to see if I could find out further information in that area, but feel like what I found is that maybe what I've discovered can be of benefit to others on this site. It is not easy to find a well trained PT in that area ,as I went to two others for that and they had learned some stuff at conferences and did'nt really understand the nature of effective treatment. I am a trained Occupational Therapist myself so I have a good basic understanding of the vestibular system,. Anyway, the long and short of this message is to tell you to go to youtube and punch in this dr's name -Dr. Shin Beh. Hopefully this will open a whole new world for you. Also, if you put in "optokinetic training" , those were some of the things I began doing far into my treatment. I wasn't ready for those exercises in the beginning . Treatment needs to be graded so you can handle it , but not overtaxing the system and making you feel worse!! hope something here helps someone, as I know how frustrating it has been for me, ie being told a few times what was going on was because of anxiety!! Good luck and hopefully I will hear back from someone, possibly with even more good information!!
