Thanks for your advice. I have decided to go to the doc. next week. I have had it x-rayed - in 1984. Will ask for physio too. At the moment when it is really bad I pop along to the local golf club spa and have a massage. Hasn't worked this time.
Taking Glucosamine with chondroitin. Just upped the dose. I also take ginger which is supposed to be a natural anti inflamatory.
I need the sun I think, although do you find that weather has anything to do with it.
