I had tkr’s first one 6 plus yrs ago. Developed numbness in balls of feet and first 3 toes on both feet even though only right knee replaced. PT seemed to help and prob went away. 19 months later ( 5 yrs ago now) has left knee done. A week later problem redeveloped. That was 5 plus yrs ago. To this day both feet numb, burning, and stiff. Motor function good in both feet other that ankle pain from both feet being flat. Wear custom orthotics constantly and have had 3 nerve decompression surgeries on my left foot being worse. Left foot also more flat than right. I suffer every single day. 24/7. Gabapentin 600 mg 3x helps a tad but not enough. No one has any answers for me. I need HELP. Anyone with any suggestions?
