However, I'm noticing that as I'm able to advance in my stretching and strengthening exercises with my ankle, my knee is getting worse. Sometimes, my knee
will completely give way and it especially hurts when I straighten my knee
; sometimes it will even lock up on me, but not for very long. I also have trouble sitting Indian style (my knee gets very sore and it's painful to straighten my knee back out -- sometimes my other knee -- the right -- hurts VERY little, but nothing like the left).
