Glad you're okay! Done there, been that....

The bars might just be twisted on the mounting stem, depends on the model.

One thing to check is the round of the wheels. Doesn't take a real hard whack to bend or ding a rim. Just rotate with it on the center stand and check for true. Most of the out of rounds can be fixed by tuning spokes. I mean literally tuning, because once all are correct they should emit the same musical note when tapped, or at least real close. A small Crescent works just as good as a spoke wrench.
