I'm sure I am experiencing sciattica. I do have a numb calf and numb foot that feels like it fell asleep. All but my big toe is weak and I have an absent reflex on the back of my foot heel area. I do have a large disc extrusion that appears to be compressing on nerves. A tms doc I spoke with said tms does not cause motor loss or loss of reflex. I know people who had legs and hips lock up from sciatica so what makes my case not tms? Is it because the abnormality is larger than most? Dr sarno says that even spinal stenosis which is painful is tms related. I'm so confused can someone give their opinion. Thanks.
