Knees seem Hot, Tingly, weak, and Numb

Hi.
I was diagnosed last year w CFS and have been on a couple meds since then that seem to help, but not always. My boughts can be minor in nature and very tough also. They can affect some parts of body, and sometimes many parts of the body.It does seem that when I have these attacks that the first area affected are my lower legs, in particular the Knees/Knee caps. They seem Hot, Tingly and Numb and Weak. I have many other symptoms like most of us.
Does anyone else have this Leg, Knee symptoms?
Thanks for any feedback.

My pain dr said the legs are affected because of back problems,
In my legs I feel like needles moving in my legs when I walk
