I tried the sound wave and after the treatment they were pushing extra hard for me to say I felt better. I felt something for sure but couldn’t honestly say better. The person who gave my knee a massage, now that did feel better! I am trying stem cells now and going on my 4th month. Sometimes I feel better, sometimes not. Have about half my cartilage left on both knees, half the bone is bone on bone. The other half still has cartilage in between, one of the doctors told me if I have no relief at end of treatment they will do something else to help. I asked will it cost more and he said no. I’m 66 and still using an old push mower to do the yard. It’s been years since I did the yard without taking any breaks every 15 minutes to cool my aching knees off and the last two times I mowed none stop once and only one break the other time. Grass getting high again. Going to go cut it in a little bit. Will add to this in a while hopefully.
