TENS (Transcutaneous Electrical Nerve Stimulation) devices have been used for years for muscle and joint pain.
Up until now, they have only been available by prescription.
AccuRelief TENS Pain Relief System are now available without a prescription and studies appear to show similar benefits when compared to their Rx cousins.
These products, which are safe, work by transmitting low voltage electrical impulses which then decrease pain perception by the sensory nerves. These devices do not work for everyone and should not be used in patients who have a pacemaker, epilepsy or are pregnant.
