I've had a second opinion from the same clinic before, a couple of times. It can be easier if that's your normal drs because then they have the rest of your history on hand too. And if one of their colleagues is a bit of a numpty sometimes they usually know that too. But if you feel uncomfortable going back, by all means see a different clinic. Just be aware that the really good drs can be hard to get into if you're a new patient.

Btw I agree with Trill, I would imagine it was cause to see your gyno.
