I didn't mention in my first post, I was riding with another guy and as we passed so he could take his turn in the front, we locked handlebars and both went down. Good for him, he did much better with some minor rash.

ER did CAT scans, xrays and I got negatives on possible major injuries to head, back, pelvis. The most visible signs of my fall, busted nose and black eye are the least of my worries

Just need to keep an eye for any sudden changes in health.
