Anyone know you I can still use my Tenz Unit for my back from the chiropractor since I've had this surgery and have the staples?

Yes, you're staples were most likely titanium. You can go through scanners at the airport, MRI machines, xrays, etc. I have had a TENS unit on my back since surgery.

Ty emlefe. I wanted ti use it last week and was afraid to. What is your opinion on wearing a medical bracelet for having the sleeve done?

I've been considering buying a RoadID recently. I ride bikes a lot, road and mountain. I was hit by a car driving 40mph while riding my bike alone in 2002. While I did get hurt, I never lost consciousness. I think it's worth the money, for sure!
