Hope your procedure goes well. I saw an ortho that specializes in foot, ankle, and knee problems about my lower leg and foot numb-type, tingling, twingy feeling mainly in the feet. I thought it might be some peroneal nerve problem, but he seems to think it's coming from my back. He used to do back surgery, so seems to have a good grasp of things I've been thru. He gave me Lyrica for nerve pain and an appointment for orthotics. I see him in 6 weeks, so we'll see.
