is the simple answer. TeNS is completely safe to use, is non-intrusive
and free of side-effects. It does not interfere with any course
of medication you may be taking and can be used on any part
of the body, except over the heart and in front of the neck.
It is important to note that if you have a cardiac pacemaker or
are pregnant, TeNS should only be used under strict medical supervision.
If you are in doubt, please consult your doctor.
