About me
In many cases, pain relief drugs are not always acceptable. Another option is a Transcutaneous Electrical Nerve Stimulator TENS machine which works by delivering small electrical pulses to the body via electrodes placed on the skin. The research evidence support the use of TENS to help ease pain, however, the amount that the pain is eased is likely to vary from person to person with the same condition.TENS units are popular for treatment of epilepsy, Parkinson's disease, and other disorders of the nervous system.
