Review on Psoas Muscle Release Tool and Personal Body Massage: Relieve Back Pain and Trigger Points with 6 Massage Heads by Bobby Porter

I like the article. I have it on my bed and use it several times a day. I became disabled due to the pain caused by fibromyalgia. I have muscle cramps and all I do is take a big ball and put it under that muscle or rub it into that muscle and it works great! In my bed I will sit on a ball under my right buttock and it will dig into my trigger point pain just by buying my own weight. Sorry if that sounds too descriptive but I love these things, I lay back to get my shoulder blades and neck pain, it's really great for my whole body! I would buy it again but since there is so much of it and you can just toss it on and use it for the things you need or detach the individual balls and focus on a specific area, this thing does it all!
