So now at home I get to figure out most comfortable chairs to sit in since I move around a lot. My daughter was over having me do some exercises was good. Yesterday the nurse came and physical therapist was here. He had me do a couple of exercises which were hard. Today walked around and did exercises. Too much - my leg swelled have to rest. It doesn't really hurt much so then I do too much need to learn a medium level. And then stop. It's all a challenge. I wonder how long you should leave ice on?
