I do all the time.

Went to a specialist doctor, walked in without a mask and one of the front desk staff tried to make me wear one & I told the nice staff member helping me check in for appointment to go ahead and cancel my appointment & walked out. I do need to see a specialist to verify that I have Ménière’s but I will find one that doesn’t have rude staff. I know I have Ménière’s, I have the symptoms & like 3 docs I have seen said that’s what they think, but only a specialist can actually make that call. I also have vestibular migraines (migraine with vertigo), doc said it is possible to have both. I’ve had vestibular migraines for over 15 yrs, the new symptoms started in the beginning of 2020. Just had an Ménière’s episode yesterday, I can verify vertigo sucks immensely!
