[size=4]I would suggest seeing a GP about your knees rather than assuming it is arthritis. I have dodgy knees, one much worse than the other, but my problem is bursitis. Sadly, the only treatment is for the symptoms, so my GP and physio tell me - cortisone injections, hydrotherapy and resting the knee in flare-ups, plus gentle walking. Before this blew up I was doing 2 x 30 minute walks weekly + 1-2 hours square dancing once or twice weekly so big changes in my exercise program. Oh well, c'est la vie![/size]
