It feels that way. At karate I felt my right hamstring pop slightly. Low, above the knee, it's sore and hurts. Put some ice on it, but it's still sore. Then my left elbow got tweaked as well somehow.
I'm supposed to have a scrimmage on Sat, but things aren't looking great. Luckily I can play both ways, so I can play right handed and not throw with my left arm and just jog around the field. Not sure how I can swing, but I'll try a few tomorrow.
It's rough getting old.
