When in doubt go to Mayo Clinic. I went to Cleveland Clinic bc that was the closest for me. Then there's Vanderbilt too. I couldn't get a diagnosis for another illness I have and Cleveland Clinic diagnosed it (over the phone) with a follow up to do the actual test. It was during Covid and they had to postpone my appt to a later date. But the neurologist called me and questioned me for about an hour. My Humana insurance paid every dime except travel and motel of course.
