I'm 84. I have had peripheral neuropathy since having chemo for breast cancer at 79. My feet are numb as well as three fingers in m left hand. I recently decided to use the battery operated cuffs that were issued to me in the hospital after the lumpectomy to prevent blood clots. My ankles were swelling. After about two weeks i found that the feeling was back in my hand and I could feel more walkng barefoot, which I do most of the time. If you decide to try some get those that you can walk around in. I like the feel of them on my legs. The edema is also gone. I figure that it's the increased circulation that has improved my nerves.
