Back in the old days...
My wife suffered a similar problem in 1993, they scanned her on a brand new MRI within a couple of weeks, and gave injections. The injections didnt work, and as I was due to be discharged, they gave her a surgery date almost immedietely, so we weren't left to the NHS.
Thank you Wroughton, or whatever housing estate you are now. Or at least the people that staffed it.
