gosh i hope they dont call that machine that gives the pain and the
other the same name? i dont think so i just cant think of it but it has
three initials like ems or something but it is to give pain and the tens
relieves pain by a shock but it is very very mild and the other is very
very strong. --------you can hear people scream when they get it in the
hospital. not funny and rediclulous and stupid.
