I fractured 2 ribs over the summer. I took a week off the bike. It seemed to me that riding was one of the lest painfull things to do. Laying on my back hurt more. That is seated riding. Getting out of the saddle hurt. Breathing hard hurt too. I took it easy no hard efforts. I was extra carefull so I would not fall and make things worse. I think it took 2 months before I could wake up and not be sore. Go easy and take care of yourself. Heal fast!
