I have been using the electrotherapy program daily for about 2 weeks. One woman I read about in the literature didn't see any relief until 3 weeks, so I will continue. I haven't noticed any relief yet, but I plan to continue trying for at least a month. It is an unusual sensation and somewhat soothing for the duration.
The machine is preprogrammed and is designed to stimulate the sympathetic nervous system. The designers had people with sympathetic nerve pain in mind. I place electrodes on very specific locations on both legs (below the knee). I'm glad I don't have to put the electrodes on the upper portion of my leg, which would be terribly painful. The first part lasts for 40 minutes. Then I place the electrodes on my hands and arms and continue for another 20 minutes.
My physical therapist was able to get the machine on loan from a vendor of his. After two days of training, he allowed me to take it home, which is a much appreciated gesture (copays every day for a month? no thanks). The vendor is allowing him to borrow the machine. If it does work, he will have a sale.
Are you suffering from nerve damage? Anything working for you?
