Re: herniated disk & emg
unfortunetly, an EMG will only show problems with the nerves if there is actual damage or constant compression of a nerve.when i had my first EMG done the tech told me before the test that it might not show all the damage to the nerves,espescially if the compression changes when in different positions or if there is ongoing irritation to a nerve root.The only thing that shows up is actual damage.mine came up negative for anything wrong but i was having numbness and tingling and lots of pain in my neck and down my R arm.I did have a confirmed(by MRI)herniation of my C 6-7 so i was quite suprised that nothing showed up.now, move forward to after my last surgery,which involved going to the inside of my spinal cord to remove what was basically a glob of slowly hemmoraging blood vessels from the inside of my cord at the C-7,T-1 level.Boy, now there are all kinds of fun things showing up on my EMG as I suffered some very significant permanent damage to my C-7,C-8 and T-1 nerves and also two spinal tracts that run through the cord.My L arm is an absolute mess(the reason for my crappy typing)and the EMG showed some very significant damage.I just would not put a whole lot of faith in the EMG, espescially if you show a herniation on the MRI and you are suffering from the symptoms that you are.You really should be feeling quite good about the test showing nothing as it means you are not suffering any damage to your nerves that could become permanent ,at least not yet.This really is a GOOD thing,believe me.marcia
