I'm 46yr old lady of height 5Ft & weight 82Kg. I can sit with folded legs and move legs/joint easily without pain But when I walk, I feel pain and inflammation just below one of my knee or maybe on the lower most part of the knee. If I keep standing for long, then it becomes even more painful to walk. I could sometimes feel tik-tik in my knee. Why?
