You know, I really have no idea what's going on. I've been having pain and instability with my right knee since Sunday. No apparent reason whatsoever. No fall, no twist, no nothing. It *is* my knee with the ACL reconstruction, and occasionally it acts up. But that doesn't make it any less annoying.
I'm finally feeling good and motivated about running again, and now I'm taking USRDs for the knee issue. Very annoying.
Anyways, I'm going to the gym tonight, and will do cardio of some sort.
