For those in pain, there is a machine that uses electro-magnetic stimulation to banish pain. You can read about it in a book on Amazon. The title is PAIN BANISHMENT, NOT PAIN MANAGEMENT ~ EVEN WHEN NOTHING ELSE WORKS ~. For a freebie preview, go to Google Book Search. You can read the first part of the book online. This is worth checking out. This machine has been in use since the 1990's and has a long track record of success. But it is a Rx device and not available for sale without a Rx.
