question: Hi doctor, I am a 40 year old female. My height is 5'4" and my weight is 64 kg. I am suffering from left knee pain with some swelling and stiffness for the past three years. I am taking Sazo 2000 and OXC 200 for two months, but had no relief. I have ANA 48.5 and CRP 7.9. My MRI showed no tears, but some fluid or effusion.
