I use the DRHO’S Foot Massager because I’m a diabetic, and I suffer nerve damage in my feet and some in my legs. I sometimes have numbness up here. And I can actually pinch it, and sometimes I don’t feel it. But after using the DRHO’S Foot Massager, it helps the circulation I find in my legs and the pain is less severe. You’ll be amazed how quickly the pain go from unbearable, to you can tolerate, to there’s no pain. I use the DRHO’S on a regular basis to keep the circulation in my feet, so I’m aware of.
