Ever Since My Complete Knee Surgery,performed 1-11-16 I Have Had

Ever since my complete knee surgery,performed 1-11-16 I have had a numbing effect in my lower leg and top of foot. The pressure is more acute when I am sitting . The leg feels like it is asleep. I walk 2 miles a day, exercise(stretching) each a:m for 1/2 hour and am physically active.

My Orthopedic Doctor recommended a back specialist but I currently keep my bacl
k in very good shape by
visiting a chiropractor once a week.
Do you have a suggestion?
