I just had a back surgery and my horse jumped on my foot, breaking my little toe. I have been using the Tendlite and I have had reduced pain and my toe which had a laceration with sutures healed in a week. I couldn't even find the laceration after 7 days. My sister who recently was involved in a car accident had a painful neck. She used it and said she had less pain the next day. I am going to take it to the barn for others to try.
