Over the last few weeks I have seen a general, dentist, an ophthalmologist, pulmonologist, dermatologist, and ENT. Every single one of them asked me what I was taking and if I started taking anything new. There is no way the ENT would have known what I was doing with the pulmonologist, ophthalmologist, or dentist as they are on completely different hospital networks.
