Just to let you know, I am enjoying my new mat. Before I got my mat I was experiencing muscle spasms in my back around 4:00 a.m. The muscle spasms are gone, but there is some tenderness when I get up from laying down. I have been only able to use the mat once a day from 30 – 60 minutes per day. My stamina is so much better now and I can do more things around the house in one day. I don’t even notice the arthritis (bone on bone) in my knees anymore. I do take FAB CBD oil daily for my knees which keeps me pain free, but my knees are feeling less stiff. I can go up and down stairs a little better. That is huge for me. The bone spurs in my shoulder always were aggravated when I crochet (which I do daily). Now I rarely even notice any pain from the bone spurs. Oh, also, my Doctor told me my kidney function is improving.
