About a month ago I stepped in a pothole and sprained my left foot. I immediately started hot/cold therapy to reduce swelling and prevent bruising. It was very painful. I had access to the iMRS probe which I used along the left side of my foot for 30 minutes at a setting of 200. I used it 2-3 times per day for 3 days. After the first 30 minute session much of the pain was gone. After 3 days the dark pink bruising had disappeared completely as well as much of the pain. For about 3 weeks I couldn’t wear shoes but I walked every day. In 4 weeks time I was able to wear shoes again. My chiropractor says it can take up to 9 months to heal a sprain. With using the iMRS I was able to cut that healing time to 4 weeks, a miraculous recovery.
