When walking in the supermarket, I had sudden pain in my left knee. So severe I could hardly put weight on the leg. It seemed to get better as I walked around. However, later as I stood up from sitting, the pain returned and I again had trouble walking. There is no pain at all when sitting or just standing. But when I try tomputnweightnon it and walk the pain is there. What could be the problem? Frank
