Hi Josh,
If you're interested in healing with allopathic/traditional medicine, you could always become a nurse, EMT, or paramedic. <img src="/images/graemlins/smile.gif" alt="" />
If you're talking about "New Age" or alternative medicine, there's crystal therapy, Flower Essences, Therapeutic Touch, Reiki, aromatherapy, chromatherapy (color therapy), sound therapy, herbs, prayer/visualization, and so on.
