I felt valued, listened to. I have seen more specialists than fingers on both hands. Most push me off on other specialists rather than try to help and coordinate my care. My new doctor had suggestions and discussed plans and differential diagnosis and steps further down the road depending upon how I am doing in 6 weeks. That kind of forethought and open discussion offers hope in the event the first course of action doesn't work as planned.
