I was in a pretty bad car accident and have a lot of back pain from my injuries. My physical therapist recommended I use one of these to alleviate some of the pain. This product makes a huge difference for me. It's easy to use and very effective. I apply a small amount of pressure to the area and it immediately relaxes and the pain starts to subside. I wish they made a travel size so I could take it everywhere!
