Yikes! Possible cracked rib.
I had a freak accident at work where my hand slipped and I hit my right side on the edge of my desk. Don't ask me how it happened, but it did.
I shrugged it off at the time but it started hurting later in the day. I didn't ride that night on my usual training ride. I rode yesterday, an easy 29-miler. Last night, I was in serious pain. OK, I'm going out on a ride today with my son, who has a new bike (another thread). I know that there isn't any treatment for a cracked rib, or a bruised one, I can't tell between them. Vitamin I will carry me through today's ride. I don't want to think about how I will feel tonight or how I will feel if I can't ride next week. Grrr.
