Karate WAS cancelled last night, so I stayed home and rested. Today I felt even better, so I actually went to the gym! Yay! All I did was a half hour walk on the treadmill, but it was something. It felt pretty good so I may try a slow jog (11-12 minute mile) tomorrow.
Anyway, it feels great to be on the mend, even if it'll be a while before I'm back to 100%.
