Review on MERRITHEW Massage Ball Single Inch by Marta Bruns

I have a 'dirty' shoulder that may need surgery and has a lot of scar tissue. Smaller ball rollers do not reach the shoulder blade sufficiently. That's a good size. The "studs" could be a bit larger and softer to allow them to be pushed or used without clothing. I can't use it on my feet without thick socks because it tickles and it hurts a bit on my shoulder because they are small and very hard, but overall it's nice. I actually lost it (or it was stolen by a dog) and am considering getting another one if that says anything about how it feels.
