Hello,,, have you got any injury to the knee?? Previously,, do you get any pain during walking,, does it limit the movements while walking?? There are knee supporting bands are available in the market you can use that while running, and include more calcium containing food in your diet, which help to keep joint strong. If pain is more you need to consult orthopedic surgeon to get examined.
