I'm going to go out on a limb here and say that pain meds have no effect on emg's or nerve conduction tests. I have had both, and so has my husband.

You've had these before, right?

If you are in distress, then take your meds. Who needs to be in neuropathy pain, especially if the meds have been helping you. They have been helping you, have they not?

You've had this since the 90's??? You sound like my husband. I gather you have had the diabetic testing, and spinal taps, am I correct?
