I couldn’t be happier. The pain was severe and felt like tendonitis. Sudden onset, rapid spreading. Now, completely gone. The Infratonic 9 is my go-to aid. It’s a godsend. I take it when we’re headed off for a day trip. I don’t leave home without it! I am a lucky woman to have access to such things – to know about them and to be able to afford them. I am so grateful.
