One of our karate students is a doctor, so I asked him what muscle it was. It turns out not to me the hamstring, but the adductor. I am not a doctor, and don’t even play one on tv. But whatever. I rested Thursday and Friday…well other than a karate demo, and a karate class in which I took it easy. Anyway, I massaged, and took ibuprofen, and rested, and my leg is feeling much better. I am still skipping aikido class. With all the rolling, falling, etc, it is too easy to tweak a knee or muscle. I might do my run. I could alway push it off to tomorrow for an extra day of rest. But I will see how I feel.
