I know this is a Surgery Section, I did have Lumbar Surgery L4/5 fusion and I am going in for these two tests on Monday I was wondering If anyone can let me know

1.With the EMG are you suppose to feel anything, would it be a good thing or a bad thing to feel anything? The worse the injury the more you feel or the less is what I am wondering.
2. Does anyone also know as well what are the Does and Donts prior to the test eating/drinks/pain meds (cymbalta,ultram or Hydrocodone) allowed to or not until after the tests? Any help would be great thank you


  • I felt quite a few things for the EMG tests that I had. In the test they measure how fast and the amount of a signal your nerves transmit. I didn't like these tests the 4 times I've had them done over the years. You will not feel anything meaningful to you. You might feel your muscles and nerves jumping around as electrical current is applied to them. I don't remember having to stop taking any of the meds in order to take the tests. Ask the Dr. doing the test if they want meds to be held.

  • I think u misread what I'm having done.........not EMG's(I've had those though) I'm having Steroid injections in the lumar spine @ L-5

  • Sorry, i replied to the wrong post
  • I have had a number of these done. You will feel the small "needles" they stick into you.....not too bad, bearable. The NCV is where u will feel the "voltage" I really cant say if the "less you feel the greater the damage" or vice versa...nonetheless,its sorta an uncomfortable test but again, bearable

  • Here are some general guidelines that seem to be pretty much the same.

    Tell your doctor if you:

    Are taking any medicines. Certain medicines that act on the nervous system (such as muscle relaxants and anticholinergics) can change electromyogram (EMG) results. You may need to stop taking these medicines 3 to 6 days before the test.

    Do not eat or drink foods that contain caffeine (such as coffee, tea, cola, and chocolate) for 2 to 3 hours before the test.

    or --

    Your doctor will advise you not to take any stimulant drugs, drink beverages like coffee, tea, or cola, or take any medication that has a sedating effect for at least 24 hours before the test.

    You need to call your doctor's office to see what they specifically want you to do. The above I took off a couple teaching hospital websites....
