Tomorrow will be six weeks since my right total knee replacement (6/21/11). Immediately following surgery I had numbness and tingling in my right foot. I was told this was possible given how bad my knee was prior to surgery. I have always been able to move my toes and the doc told me the symptoms would eventually go away. Over the last 6 weeks the numbness and tingling have given way to burning. And although the burning is getting better it seems to be worse after exercising at home, physical therapy, and is really bad while laying and sleeping. Given the need to move so much while laying down I am not getting much sleep. Can anyone suggest sleeping positions that would be more comfortable?
