Back pain results from a malfunction in your nervous system and is generally the result of injury or an arthritic condition. The National Center for Complimentary and Alternative Medicine says that magnets have a history of successfully treating pain.
Your body sends pain impulses to your brain, and they travel on positively charged ions. Magnetic therapy is a non-surgical treatment that uses negatively charged magnets to block the positively charged pain impulse from reaching your brain. The magnets may be in a back belt and cover the sore area of your back.
The efficiency of magnetic therapy improves with consistent treatment. If your back pain is from a genetic condition or arthritis, the pain probably will not cease immediately. However, if you wear the back belt whenever possible, magnetic therapy consistently treats the area and blocks pain.
If you have an embedded electro-medical mechanism or are pregnant, do not use magnetic therapy. In addition, for at least 2 weeks after having a cortisone shot, avoid putting magnets over the area where you had the shot. Never cover a bleeding or open cut with a magnet.
