The St Jude reps told me on several occasions not to drive with them on, my husband questioned them because I am in so much pain in the car. They each said that the chance of accident was too great because the "jolts" that could happen when you make sudden moves. I could see that because I get those jolts often, well from the cervical stim anyway.
I forgot to turn them off one day before I left my office because I was in a hurry and realized after I started driving that they were both on...I was nervous
