A few weeks ago, a friend of mine decided to join a kickboxing boot camp. It was a pretty intense work out, but she came out feeling great and eager to use me as her human punching bag. The next day was a completely different story. Her calves hurt so bad that she almost couldn’t walk. I did a quick assessment and there were no obvious signs of an injury other than the fact that it hurt when the muscle at the back of her leg was poked or stretched. So I waved my magic hands and told her that the pain would be gone in a few days. Presto! She was cured two days later.
