What’s Going On With My Knees?

I’m feeling a slight sensitivity in the small toes of my left foot, so maybe they;re being abraded now, rather than the balls of that foot.

Also my knees still seem sore and there is no clear pattern to this.  I’m hoping they are just getting used to carrying more weight/stress, as the impact on my heels lessens, and they will adjust in their own time.  It is worrying – I’m not used to not being able to flex my left knee completely.
