I have cortisone injections in my knees for arthritis successfully before (in February and Last September) and they have worked well. I had them redone 2 weeks ago and gradually the pain has worsened and my right knee that is not as arthritic as the left is now worse! I can't see the consultant till next Friday, I don't understand it even if they haven't worked surely they would not have deteriorated so quickly?? The pain is different sometimes it is a singing burning pain and moves over the kneecap and sides of knee and can be quite constant....it hurts when I walk but not always, but hasn't been stiff or affected my movement, just feels very unpleasant painkillers aren't doing much ...it's scary as I don't know what'll I'll do if it hasn't worked. Any advice welcome thank you.
