Papillon back massager

I get these episodes where I have knots and tension everywhere and it gives me headaches and tummy aches, but I’m also a recluse so not always up for a massage. Please get this. I use it from my lower back to the back of my skull and sometimes lay on top of it and fall asleep. It’s not an exact science but when you learn to roll it over the right places it can bring a tear to your eye.
