My back condition

I had an MRI scan on my lower back on 11th April at the Freeman Hospital.
I have an appointment with one of the consultant neurosurgeon's team on Friday 25th April - presumably to discuss the results of this. I hope there is something that they can do to get me out of the hole that I'm now in with this back trouble. It has gone on for six months now and I've been off work for something like three months.
I'll need to have some idea of how long I'll have to wait for any treatment; and of how soon (and how expensively) I could get it done privately.
