I've had a stimulator for my lower back for 5 years. Although it really doesn't help with pain. It takes care of the stabbing pain that goes to the top of my hips into my lower back and down my legs. And I know for a fact. I would not be walking without it. But as far a the tens unit. I never could use it messed up my pace maker.Good luck if your thinking about getting an internal stimulator. You are apt for an infection and I never understood why. Maybe because of the biologics I've been on.💖🙏🙏🙏🙏

Thank you!
