I know this is an old thread but I would like to ask chronic pain users of TENS a question. I've had Fibro for nearly 40yrs, I'm nearly 60yrs now. I also have TMJ and now Arthritis . I started using a TENS machine a few yrs ago to supplement my opioid medication and all was well for a while. Then one day I had the most enormous electric shock up my back and decided to stop using it. Nothing is wrong with the machine as others have used it since and its been checked out by a qualified electrician.

I continued to get the electric shocks up my spine even without using it so I discussed this with a friend. She is my meditation teacher and said I may have set off my Kundalini energy?

Have others had this 'shock' or been told this?
