i was taking a drug called diclofenac for arthritis in the knees. bone on bone in the left. i was using it for several years. then the pain in the feet got so bad i could not walk either. blood work came back and my kidney functions were off the chart. that med caused the gout but i never had redness or swelling. doc prescribed Uloric. very expensive but luckly was able to get it down to a affordable price. but then the knees got so bad could not walk again. need a new one and some orthoscopic in the other. but got euflexxa shots for both knees and within days back to almost 100%
