Thank you for the advice. My situation has rapidly deteriorated, so any excercise is a certain no go area at the moment... I have surgery once they stop messing about with the dates & things will be even worse for a while, but have been advised that relaxed swimming can help as it is very low impact on joints. Hopefully, later if things settle, then I may be able to go walking & take it from there... Diet is extremely important from now on & I have researched the best nuitrition for my situation. Hopefully thing will start to improve soon...
