I am a neurologist and would be happy to lend some thoughts, but obviously I will need much more information than what you've provided.  Do you have access to the tests and reports that were done at UCSF? If you so, please collect as much of the information as you can including the NEUROLOGY CONSULTATION notes (if you saw a neurologist) and upload them with some more detail as to everything evolved over 2 years from playing tennis to not being able to stay balanced while walking and upload all that to
