Well, for starters I have been having an issue with my left knee for months. I can bend it but keeping it bent hurts in the left back, I can t squat down at all and if I try to straighten it, there is bad pain in that same area. It takes a great while before I can get it close to straight after having it bent. And now, my left foot started having pain as well a few days ago along with some swelling on the top of it with an elongated shape to it from toe to ankle. It hurts like there is a rubber band in there and every move I make with my foot or ankle is pulling the rubberband or loosening it and I can feel it getting tight and loose. I can feel it within my foot which hurts, and outside my foot with my hand. I am not sure what is going on but I m not sure what to do.
