I had a strange pain in my foot for months, and then rather suddenly that portion of my foot went dead, ie, no sense of feeling. A part of my foot was in-sensate for c. 3 years. It was not on & off, the back & heel of my foot were dead 365 days a year.

After using the detox foot patches on & off for awhile, the sensation returned. A total of about 27 patches were used. Is this "scientific"? No. It is my personal experience and that is all I can say.

I originally thought that you didn't have to supplement while using the patches, but an article I read by a woman convinced me that I should add some minerals (I only did a few times, though).
