I had my knee replacements 11 months apart in 2016;and 2017. I have had numb, tingly, burning in both feet since 2:weeks after my second knee. I had tarsal tunnel decompression in the worse foot 3;yes 3 times since with no relief. I am so sorry I didn’t just leave it be. My left foot is so bad from nerve damage from the surgeries. Nothing really helps in fact most topicals I try make the burning worse. I am on 1200 mg of gabapentin which I am trying to wean off. Side effects are terrible. Not in a good place but just glad I can walk. Feet are strong so far fingers crossed .
