First, Im sorry you're dealing with this. It sucks! Ive been dealing with a nightmare of vestibular problems for the last 10 months. The good thing about pure vertigo is it is very likely fixable. Kuppersmith told me they dont treat dizziness and told me to go back to my primary care. He was of little help for my case. Here is what I would do if I were you-
1. make an appointment with your primary care asap. Ask them for a referral to Lindsey Roberson as suggested above. Ive seen a number of vestibular PTs and she is as good or better than anyone you can find in Houston. You will have to have a referral for any PT. Any doctor can write it for you though.
2. Make an appointment with Dr Brammeier or Dr Hill at S&W in Temple. They focus on vestibular problems. Do this NOW because it will take weeks to months to get in to them. If the Epley maneuver doesn't help you, you will likely need additional testing and they will be able to do that. Unfortunately their PT guys missed my problems that were later found by Lindsey Roberson above.
Other good resources- Dr Patki at UTHealth in Houston. He was able to finally correctly diagnose me within seconds when a slew of other neurologist and ENTs failed. Again, some of these doctors can take a long time to get in to so don't be afraid to make an appointment and you can cancel later if you don't need it.
TIRR Memorial in the woodlands has good vestibular therapist also.
Good luck and feel free to email me at toledo321 at aol.com if you have any questions, need neurologist suggestions, etc.
