How do I know I have arthritis

Arthritis pain can begin suddenly, but it is more likely to develop slowly. You may feel a grinding sensation in your knee as you move. You might even hear cracking or popping sounds coming from your knees. You are most likely to notice a restricted range of motion when you climb stairs or in other daily activities. Arthritis can make it challenging for your knee to perform previously simple movements difficultly or impossible. As arthritis progresses you may notice changes in your knee s appearance. Your knees can start to point toward each other or bend outward.
