For me, Prana mats have been life changing. Literally. I suffer with chronic pain, muscle spasms. fascia disorders, and permanent nerve damage. My daughter gave me Prana mats for Christmas 3 years ago. Best gift I have ever received! I cannot live without them! My nerve damage prevented me from sitting and I battled flare ups on a daily basis. When I use the Prana mats, I am able to sit without experiencing muscle spasms. It is nothing short of miraculous. I follow blogs for people who have pudendal nerve damage, fibromyalgia, and the mesh injured. For those people, there is no relief. Even drugs and pain meds do not help. Prana mats are the only thing that I have found that actually give me relief. I have asked the company to conduct research on people who have nerve damage and fibromyalgia. Somehow, the lotus petals poking into bare skin manage to quiet nerve flares and calm fascia flares and release muscle spasms. It is truly amazing. I use the large Prana mat and pillow when I am watching TV. If I have a bad flare, I will recline on the Prana mat until it ceases. I sleep with the Prana pillow, adjusting it throughout the night to calm spasms. I tuck the tiny mat into my pants to drive or to sit. As long as I have the lotus petals poking my skin, my life is actually worth living again.
