Yes he trained at Mayo, but told me the ENT to deal with the issue was one I had already gone to and was to say the least nasty and unprofeessional... in fact got upset that I asked a questions and he got upset and walked out of the office. ....he trained at House. BTW my dizzy/vertigo non-stop for 8 months was caused by a new medication that my pulmo recommended when I returned from having Valves inserted......Eliquis.....I was the one that researched that and found at leat 8 case studies and a NIH research article re warfarin vs Eliquis. When something "acute" (sudden onset) happens look at what has changed in your treatment first and rule them out, House Clinic I think would be your best bet. Can you get your physician to do a referral? Sometimes that speeds things up
