Cracked several ribs. All the same way. From wrecking a dirt bike or four wheeler.
Only tight wrap when doing physical activity, like riding your bike again. Don't tight wrap for any other reason though. Begin deep breathing and mild stretching exercises after a couple of weeks. Taking it easy is the best thing you can do for the first 2 weeks. I've never been a believer of nutritional pills, so I just increased my calcium intake through natural diet. Not very hard to do. Buy some blocks of cheese, cut them up, and grab a chunk every time you open your fridge. You'll find yourself going to the fridge a lot more out of boredom from lounging around your house a lot more.
Alcohol was my chosen pain reliever. Last time I cracked a rib was this time of year, and it was pure hell. Not only did I have a bad cough, but my hayfever was especially bad that year.
