what can I do for a tingly left foot and I seam to have an extra layer of something in the bottom of my foot after a sciatica pain in my back that went from my lower back and left leg all the way to my toes? I had the sciatic pain years ago. did go to the Dr.s  and am real careful about my back now. but the tingly feeling never goes away. I had sciatic pain years ago. the morning it started. I did get out of bed and hurt so bad I just flopped back into bed and would not move. All the Dr.s that I wanted to go to were either out of town or on vacation. I did get it taken care of. saw my family Dr. and a surgeon. they said that my lower back did have artheritus in it but there was nothing to do at that time. I have had a tingly foot like its asleep all the time ever since. It also feels like I have an extra layer of something in the bottom of my feet. they did that spiked wheel test on me I feel every time and every where it touches me. I have to be real careful with my back. If there is something really heavy I ask someone to help. If I twist wrong, or don't lift properly I know about it right away. I have slipped on the ice a couple of times and landed on my back but have not had anything like the sciatic pain again thank goodness. I'm just wondering about the tingling and the feeling of an extra layer in the bottom of my foot. will that ever go away? I have shared this with Dr.s several times but I never get an answer. What can I do about it?
