I went out for a run and took a hard fall when I hit a patch of ice. I broke the fall with my left arm. I sat there for a minute evaluating the damage. Nothing was broken, but within 24 hours my shoulder was killing me. It was difficult to sleep and I thought I wouldn't be running again for a few weeks because it was so sore when I moved my arm.
I started Laser Therapy treatments on my shoulder 2 days after the fall. After only 3 treatments, it was 80% better. And it only took 5 treatments in total to heal it. I was very happy to be running again so soon.
