I have been using the device for about a month and a half and btw I have had tremendous results, until recently... All of the sudden the current is ridiculously strong. I used to use level 5 but now when I turn it up past one I can feel an electrical pinching and I get really dizzy and light headed. I think it is an issue between the connector from the wire to the device. For some reason I cannot get it disconnected now, it is totally latched on there. I don't want to use too much force because I think I'll break it. What should I do? I don't want to stop using it because it has helped me greatly, but I don't want to keep using it if somethings wrong. What happens if the output is too strong can I get hurt? Is there an IT # to call?
