I am a 67 year old woman, I broke my humerus with slight displacement 6 1/2 weeks ago. I was in a collar and cuff, sleeping in a chair for 5 1/2 weeks. X rays show bone growth and now working with physio. I am doing everything I indicated and a bit more, the main difficulty is pain. I hate medical pain relief many of which don't suit me. Will a tens machine help. Prior to the injury I worked in the gym twice weekly and swam 3 miles weekly.
