Here is a link to part of a blog I wrote on managing pain. There is some dietary advice in this section: http://www.avogel.co.uk/health/muscles-joints/blog/2013/12/dealing-with-pain-part-2/#comments
As regards exercise, it can elevate feel-good chemicals, especially if done in sunshine but don't try to make it too arduous as you will aggravate the joints.
Best wishes
