I have also got a similar problem with this numbness from a TPF/surgery. Part of the top of my foot, and a portion down the side, from the knee down to the ankle, left of the scar is numb.
I know this is an old post, but I would like to hear about the recovery time for this type of issue. I am 9 weeks from surgery.
Did it just take time for the numbness to just disappear and return to normal.
