I just joined the forum 15 minutes ago after reading a number of posts. But couldn't see anything right away regarding my question(s). I had my left knee replaced middle of April - high flex zimmer- went back to work two weeks ago and am finding that tough. But my knee is still so warm to the touch and I just can't get comfortable at night when I go to bad - I toss and turn - toss and turn - I think it's because of the heat of my knee - or is it??? When does it cool down? Or does anybody else have some ideas on how to deal with the heat and the restlessness that it seems to create?Thanks
