I was supposed to have a 10 week followup appointment from a surgical procedure. Instead had to wait 17 weeks only to find at the meeting I was seeing a physician's assistant who could not answer my questions. Should have been told before hand. I was not the only patient neither who expected to see the Dr only to be surprised.
