I wear mine all day too. I don't usually have it ON all day but I use it throughout the day to help manage the pain levels in my ankle. Since I don't take meds for the pain the TENS is really all I've got to help the pain level in my ankle stay at a manageable level. Thank goodness for my wonderful physical therapist and doctor who worked to get me one. I run the wires down the leg of my pants and wear it all the time.
