Poetist, Did you have the test done?
I've had a few SFEMG's and EMG's. Maybe it's because I have nerve damage from a B12 deficiency but I thought they both hurt.

Abby has had the SFEMG where you don't have to "participate" and contract a muscle group while the test is being done. Most doctors do it where you have to repeatedly contract a muscle.
You'll definitely feel it. Whether you think it hurts or not is often a matter of perception.
They normally do the forearm, shoulder or forehead. Some doctors do more than one muscle, some don't. They never do the chest wall muscles - too dangerous.
If you had it done, I hope it went well. And that you don't have to wait weeks for the results! It can take awhile.
