Those suffering from arthritis typically report soreness around joints, which is worse after prolonged sitting, standing, or inactivity. Pain can get worse when you move, like when you bend your knees. You may notice popping or clicking sounds in the affected joint(s) with movement, and the joint may be sensitive or painful to the touch. Arthritis can also cause pain when you exercise or work, and the pain may go away after you stop doing that activity.
