As am I, my mother was crippled up with Arthritis. Her condition was much more severe than mine (she was dead before she reached my age in any case) and, of course, treatment was of little or no help. Her arthritis was mainly in her knees and the only treatment was to be taken once a week by ambulance to a Spa town to sit in a mud bath for hours. She complained rarely and was very stoic. But she was a good predicter of the weather.
She would start telling us it was going to rain or there were going to be gales about three days before either arrived. Of course we never believed her - thinking it was 'an old wives tale'.
I go to the Physio every six weeks to try and keep my body as supple as possible and she has been telling me for years that air pressure has an effect on arthritis and similar conditions. Now I see in today's paper that some group has done a study on weather and its effect on conditions such as arthritis and has come to the conclusion that such conditions are indeed affected by both wet weather and windy weather. Seems my dear old Mum could have told them that years ago. They only studied 2,500 people with the condition, which seems a small group to me, but it does confirm what many sufferers of arthritis know and have known for years - our aches and pains are very good at predicting forthcoming weather - certainly better than your average pine cone.
