Natalie, I wish I could offer an opinion about your symptoms but to be honest, your situation is so complex I wouldn't know where to begin! I tend towards it being a withdrawal, however.
As for the Oxford score, it's a means of getting a sense of the patient's experience with their problems vis a vis your knee (obviously). Often times, they thrust it under a patient's nose in clinic and expect them to complete it on the spot! Much better that you have time to consider the answers and fill it in at your leisure. But it's important that you remember to judge each answer on the whole of your experience over the last 2-3 weeks at least. It's awfully easy to just think of what your knee is like know. And do be totally honest, no marking things down! :wink1:
