In last two weeks I have experienced knee pain. It hurts to squat, the knee becomes stiff after sitting for a few minutes makes it as little painful to extend the knee but once I am up and moving it feels fine. The stiffness and mild pain is usually on the outer knee and some times the knee cap, no sweeping, no visible change in my knee, no redness, not hot to the touch. I also have popping while going up and down stairs, have no idea if that is relevant...
What can I do to get rid of this issue? I have not had any injuries, or falls of any sort. I have never had a problem with my knees before this is the first experience.
