Magnet therapy may be practiced by a doctor or bodyworker or may be self-administered. It's best to work with a reputable and experienced practitioner who is knowledgeable about the therapeutic use of magnets.
The magnetic devices available over-the-counter vary dramatically in size, shape, strength, and price. Smaller devices, such as those that can be taped to the wrist, cost around $25. Magnetic insoles can run about $100, and you could spend about $300 to $800 on a magnet-filled mattress pad. Be sure the product you are considering has a refund option, and try to buy any magnetic products from a reputable vendor.
