I am not familiar with this other then this would make me worse. I know we are all different but having an electroid on my rsd area would give me so much pain and also delayed pain. Does your husband have sensitivity issues? It is very concerning to me that they would sell a product like this without a person to at least teach you how to use it properly. Is there another doctor that you could call in your area that could? Maybe if you call the company they could give you some direction. I am so confused so the Dr is bringing on a law suit to anyone who says anything negative? I think if this is the case you need to find a new direction. This is very odd. I hope your husband gets relief
