My husband was hit with an IED while in Iraq. He now has bulging discs in his lower back and one was completely replaced with an artificial disc. He can not have normal ex rays anymore and has to carry a card with him to the airport because the artificial disc has metal in it. So my question is could he use this producut for the pain he still has from the other bulging disc?

Because it's electronic? Sure, as long as he doesn't walk through an x ray machine with it, which he wouldn't anyway. Read the manual carefully.
