Oh, my, it does sound like that doctor hit a nerve!

Do you have any Lidoderm patches? I'd ask for an RX for them if your insurance will cover it. Placed on the back of the knee, they will help that nerve settle down. If you get relief from that, even if it is temporary, then I'd get another opinion from a doctor not involved. Damage to a nerve can heal, but it can take a long time.

I have found for myself, that any work in the feet, can leave you with some pain issues. You could also try putting 1/2 Lidoderm on the top of the foot, to see if that is where your pain is being generated. I had surgery on my instep of my left foot decades ago, and it still sometimes pains me. It was numb for years after the tumor was removed, but as I have aged, that foot seems stiff now, and the ankle hurts sometimes all night long!

You have my sympathy, because it seems like many times doctors do something to people, that is invasive, we get left with stuff/pain for the future.
