The shiatshu machine offered unbeleivable relief,and it does stimulate your nerves and muscles. I used it safely for over a year and a half,and one day I started twitching like mad after I used it, never twitched before then.
So I don't know weather it was good or bad. But since I hate to twitch, I often wish I could take that one day back.
Yes I had pain,burning, & prickling. But then I had buzzing,crawling,twitching, & vibrating. It sucked big time!!
So I decided to retire my old friend, and put him in the garage out of reach.
