@GrimpenMire I've had private cover for over 35 years and used it a lot. I have also paid for consultations that were for conditions not covered by insurance. My family have done the same so between us we have used private cover x 4 adults for 35 years.
I've been very happy with all my consultants bar two over all those years and never went back to them.
I don't know if you are still reading or open to advice but there are a few points.
The first is that if you went via a GP, they ought to have written a summary of what your have and tests done.
Did they?
The second is that you usually get around 45 mins for a 1st appt with a private dr. He may have felt he wanted to cut to the chase and the options of investigations you were fairly limited, regardless of what you told him. Does that make sense?
I agree that he could have read your notes beforehand BUT some people prefer to scan them quickly and talk to the person face to face. We don't know- with respect- what your notes you wrote were like. Playing devil's advocate - really!- they could have been jumbled, illiterate, hard for him to understand. We don't know. I'm not saying they were, but in principle a dr could get something in writing from a patient that was unclear.
As you didn't self-refer but went through your GP, the onus was on your GP to send that summary.
I think you have just been unlucky. There are good and not so good drs and they work in the NHS and privately. Some have great bedside manners, others less so.
My advice would be that if this dr didn't measure up, you find another one. Choosing a consultant if you are paying is like anything else- buying a house, buying a car- you need to shop around to find one you like and who is good. Obviously this can be expensive and it's not an option for everyone.
I think you could contact him and your GP and politely state that you felt you weren't given enough time in the appt to convey your condition - if that's the case.
