Sincere thanks to all of you who have written. Your kind words & good advice have given me the boost I needed when I see the Rheumatologist next Tuesday. Being assertive with doctors is not one of my strong suits! Special thanks for the PMs...informative, insightful & encouraging. I will update the thread as & when there is news.
                   Mudcatters to the rescue once again!
