What you are describing is called vertigo.. It's a hullusination of motion or spinning. Almost ALL causes of vertigo are due to some disturbance in your inner ear. examples can be wax build up, blockage of ear canal, or your Eustachian tube, infection also know as otitis media and a very well known disorder called meniere's.. Some even have vertigo with migraine disorders and allergies as well as tmj disorder.. I myself as you know have vertigo..
I know it can be a very scary feeling... Vertigo is connected to anxiety, almost EVERYONE who experiences vertigo has anxiety second to this disorder. You can feel anything from a sinking feeling when standing, to a swaying or motion sensation, vertigo can also cause you to feel like everything is spinning or moving.. There are many test that can be done to see where the vertigo is coming from.. I can tell you this, anxiety and stress actually intensifies the vertigo so if you can TRY not to get so anxious when you feel this way. believe me I know that is easier said then done, vertigo almost instantly throws me into a panic attack.. Medications such as xanax or other benzo's can help relieve vertigo, as well as over the counter meclizine/antivert, these drugs could be some what sadating making you feel a little drowsy, I myself use xanax if I am having a really bad vertigo day, this seems to take the edge off the symptoms.. Sometimes we have inner ear problems that we don't even realize until we visit with an ENT or neurologist that specializes in these disorders. I know you have a neurologist appointment coming up.. Make sure you address to him that you are experiencing VERTIGO.. Cause this is what your symptoms are very much leaning towards.. Let me know how you make out, keep me posted. Hope this helps a little... I know first hand about vertigo.. I am a suffer myself..
