Earl and I both have had wonderful results with the mat. His back pain is lessened greatly and he seems dedicated to spending more time on the mat. I had a shoulder injury which has given me pain (mostly at night) for 15 years; that pain is totally gone. Since my cancer diagnosis, I have been spending at least a full hour daily plus sleeping on it at night. Pathology report came in today and the cancer cells have not spread to my lymphs and the tissue surrounding the lump also came back clean.
