Magnetism and the human body have always interested the curious. Electricity and magnetism are certainly areas where we do not have all the answers. This inventor is trying to use a magnetic pulse to short circuit the pain pathways. He has already succeeded for migraines. In 2000, the three inventors filed an application for a patent. It detailed a portable device that presses against the skull and shoots magnetic energy into the brain, expunging a migraine before it starts. One study published in Neurology called such technology a “major step forward” in chronic migraine treatment.
Imagine if he could succeed on back pain? Perhaps I would be out of job.
