I wonder what was in the referral letter from your GP? You were expecting to speak to the Consultant about one issue, could it be possible that your GP mentioned some other part of the spine?
I would ring the Orthopaedic Secretary and ask what was in the referral letter. It seems strange that a Consultant only deals with one part of the spine - the one I worked for had an interest in hand surgery so his first Clinic on a Monday morning was for those who had done silly things over the weekend - i.e. put their hand in front of a lawn mower
.......... who had been seen in Casualty and referred to his Clinic. Otherwise he and the other Surgeon dealt with the whole spine etc..
If you send me a PM with the Hospital I will look at the Surgeon's detail to whom you were referred to see whether I can find out exactly what he/she deals with. I am intrigued
