Nooro foot massager - A WARNING

I have posted several questions and comments concerning the Nooro foot massager and PN on this site, but this time I am posting about a negative experience that happened to me on November 8th. I could find no way of contacting the company about this and waited until now to give me a chance to see how bad this situation was.

I had my Nooro foot massager lying out , for an extended period of time, with the control unit connected but not turned on. I went to grab the unit by the mat to use it and my right hand received a MAJOR jolt of static electricity. While the results of the jolt are ligament pain when I try to extend or stretch my arm and hand which mainly occurred in the Carpal Tunnel area of my right wrist, there has been no reduction of movement.
I talked to a physician friend of mine who suggested we just wait for about 6-8 weeks to see what my body does to heal the issue. That is what I have done. If the problem persists, I should see a hand specialist. Have decided to forego that, as it has gotten better over time, but still have some minor ligament pain when I extend my right thumb.
Basically I have decided to live with it but wanted to give others a headsup.
