Evoked potential test

I’d like to hear from anyone who has had an evoked potentials test. Was it painful? Was it useful? Would you do it again?

I have not had any experience with the Evoked Ptoential testing. It seems like this mainly used to look for MS.

I have had a nerve conduction study and didn't find it unduly painful. Some of the shocks were a little uncomfortable but it's pretty quick.
