Hi, I happened to see your post. I had TKR for my left knee in 2012. I still have pain in the bottom of my foot, tingling, and sensitivity to cold. More pain if I don’t keep my foot warm with wool socks, slippers always in my house, sometimes little charcoal activated foot warmers and good boots, in winter, the boots. I put Aspercream with lidocaine on the bottom of my foot and a wool sock at night, summer and winter. It doesn’t bother as much during the day when I’m busy etc, but nighttime is unpleasant. I hope you have had better luck. Mine isn’t going away. But you do learn to live with it and make the best.
