I would head for Mayo Clinic in Rochester! Either have your PCP do a referral or do a self referral. I was dizzy for 8 months plus terrible episodes of vertigo until I started doing my own research. I discovered the culprit was Eliquis that I was switched to from Warfarin was causing the problem. Well documented in the literature if you look! Definitely would go to a large well-known medical center......you are so close to Mayo!
