Thank you for your response - very much appreciated. I will definitely read your links. I have had a quick look but there are links within the links! What kind of lifestyle changes are you thinking of? I stand at my desk at work instead of sitting which has helped immensely. I'm exercising still - not as much as I used to but I'm hoping I can get back to the same amount. I'm trying to not be tempted with takeaway food now living in a city as I find a good diet helps as well. I have always said one should treat their body like their car - you wouldn't put bad fuel in a car and expect it to run well! I take 1mg of Prednisone twice a week now and putting up with aches as I hate pharmaceuticals. Any suggestions on life changes would be appreciated.
