Read page 31 of Dr B's guidelines (Second last paragraph) says:
"Ice (vasoconstriction) and electrical stimulation (muscle spasm and trauma) should not be used."

This document can also be found under the first topic here on this site titled: "New To Lyme?.......Start here!"
I discussed with my LLMD and was told to avoid use. It's not recommended if you have lyme infection.
If you do decide to use it on your back, avoid placing it on your spine.
