If you are worried, by all means try to get a consult earlier. Perhaps you could get a consult with a doctor who works for the NHS and a private practice? They may be able to squeeze you in earlier.
Some patients (both UK and US) have had surgery and offered very positive reviews of
Mr. Nick Boeree, and you can find their posts and PM them in the post-op forum.
Also, many patients at our
UK sister site can help you out too, especially "Sir Alastair..."
Tell us more about your spinal history when you can. Better yet, pls add this in your signature using the "User CP" in the upper left.
