I had a sharp pain in my right Achilles. It was a 3/10 when walking and 6/10 when running. I couldn't run more than 1/4 mile without pain, which was especially bad being a distance runner training for a half marathon.I had 6 laser treatments while training for my half marathon. I was able to compete in my race with minimal pain. Since my race, I had 3 more laser treatments. I have had zero pain for my last 2 runs, which is pretty much a miracle!Renee D.
