The Rhab I was just in let me use the tens while I was there,and they do have a new portable one that works very well on my neck and knees so on.
They are not expensive and if Dr. approves like mine did took it home..The
big ones well I like the portable..Yes I would need a full body one to stop
all the pain. I to would rent one,first have them show you how to use it,we are all different,I would say are you kidding a few yrs. ago,but couldn't afford it then anyway.. Hope you like it.. Hugs to all Sue
