I thought the constant tingling would drive me crazy when I first began the trial...then I realized it felt good. I had both cervical and thoracic St Jude stimulators implanted in June 2011 and the stim doesn't bother me one bit. It is such a great comfort. There are different settings and frequencies that I didn't feel as comfortable with, it takes some programming and playing with them to get that good, ahhhh feeling

I am so happy that I got both of mine!!
