My issue with my TKR in the left knee, is not pain. What I have is numbness and a hit of tingling on the top of my left foot above the ankle, and a little bit at the knee itself. As I mentioned earlier, it has been exactly one year since the surgery. I know that nerves take quite a while to heal and I'm hoping that this is simply part of the healing process. I am 78 years old as I said and have type 2 diabetes, but my blood sugar is pretty much under 7 on the A1c. I'm trying to find out if anyone has experience prolonged numbness or tingling. I was checked by the surgeon about six or seven months after the operation and he said things were looking very good, but I know that nerves can be damaged. My concern is that this is not diabetic neuropathy oh, but I'm thinking it's connected to the knee because prior to the surgery I had no problems in my left foot whatsoever. Hopefully someone out there can give me some encouragement or some answers. Thank you very much.6
