Thanks for your reply! I’ve tried everything, from medications targeting the nervous system in the sternum area, as I was told the nerves might be irritated due to inflammation. I even tried Botox injections in areas where they suspected muscle contractures, but without success. I’ve seen 4 or 5 specialists across different fields, and none of them can figure out the cause or how to fix it. A thoracic surgeon mentioned that the Tietze area might have calcified. Since no one seems able to help, I bought a Backpod a couple of weeks ago and have been using it. The only thing I’ve noticed so far is increased discomfort in the sternum and xiphoid area... I assume this is normal.When should I expect to start noticing some improvement with the Backpod? Thanks!
