First, I wanted to tell you what a huge blessing that mat has been for me personally. I’ve had it a week. As soon as I got it, I camped out on it b/c I had overworked myself in my practice the previous 2 weeks and was in so much pain that I had to take a week off. I had terrible tendonitis in my shoulders, elbows, wrists and hands. I also had ongoing issues with foot/ankle pain (for years) and recurrent neck and hip pain (for months). I camped out on that mat pretty much the 1st day and here are the changes that I noticed: 1. Foot and ankle pain – completely gone. 2. Neck pain – completely gone. 3. Hip pain – completely gone. 4. Shoulder, elbow, wrist and hand pain… still significant but getting better daily.
