TENS MACHINE 3-IN-1 FOR CHRONIC PAIN TREATMENT, Are you suffering from chronic pain?  This little device could provide the pain relief solution you have been looking for! How does it work you ask? The brain can’t receive two stimuli at one time from the same area so placing the electrodes over the area that you are experiencing pain, results in the brain feeling the TENS stimulation rather than the pain you are feeling.
