I would like to also suggest that you ask the new neurologist if you
could go see a Physical therapist to help you figure out the best placement.
For the Tens unit. I have one, and I have had great luck with it on
my shoulders and my arms. WHich is were its been used the most.

But I had a need to use it on my legs and was in PT and the therapist
helped me figure out how to place it.
