I have a broken fifth metatarsal bone and torn ligament tendon in my left ankle. This arrived one day ago and I’ve used it and I’m feeling some relief. It’s still too early to tell if this is worth a product but so far so good. I have always had pain in my neck and swelling in my neck and I have been using this as well for one day and feel incredible relief already! I will give this a five star because it’s pretty darn good ?
