Re: The relation between the sciatic nerve and the foot being swollen and cold
They do test your feet with the EMG and sometimes with the Nerve test that usually goes along with it (That one uses patches). They are trying to determine the extent of injury to the nerve and what exact nerve is causing the pain or damage. To correct the entrapment, they have to determine exact nerve. I have had one fusion surgery and getting ready for another surgery to try to get rid of the entrapped nerves. I have had at least 4 EMG's, one discogram, One cat-scan/dye(same as Myelogram), One MRI/dye, 4 regular MRI's and enough x-rays to glow in the dark (LOL). The worst thing to date was when the temporary wire fell out of my spine when they tried to implant the spinal stimulator. (never got a permanent one). Spinal Headache! Ouch!!
