Thank you for the replies. They are both of help, as at the moment, I am still awaiting to be referred for a sooner appointment with a specialist. Its hard because to date, I have had doctors scratch their heads and tell me, my guess is as good as there's as to whether things will get worse, or I have been told they won't get worse, just up the painkillers (when judging by the scans, things have already got worse, as has been said). It is difficult, being in a lot of pain, having scan results I have little understanding of, and am not getting the answers from the doctors and am having no treatment at the moment, other than painkillers...thank you again, and I will keep you posted.
