I’ve suffered two different ‘bruised rib’ injuries in my 15+ years of karting. Both times it was simply from too much grip and repeated bruising. Also, of importance to mention BOTH times, my ribs were actually ‘cracked’ and when I originally went in for a check-up and x-rays, the films came back as negative for a fracture. The reason being, they were stress fractures that weren’t detectable. But several weeks later, during a follow-up x-ray you could visibly see the ‘fusing’ or healing that had taken place.
My first advice is to stay out of the kart for at least 4 weeks. That might be a hard pill to swallow, but if you’ve only bruised them so far, you don’t want to fracture them completely. Here’s a few things to consider:
Doctors and modern medicine offer you NO TREATMENT for broken ribs other than painkillers.
When you really do have broken ribs, it only hurts when you breathe, cough, or sneeze. In fact, it hurts so bad when you sneeze, you can just start your tears prior to the actual sneeze. Also it hurts when you recline at the wrong angle, bend over at the wrong angle, or lift anything you normally would.
Everytime you get back in the kart, you just set your healing clock back another 4-8 weeks depending on your healing capacity.
The Ribtech Seat is a great option as is the Ribtech Ribvest. I have yet to see a customer reinjure their ribs after switching over to a high quality vest and seat combo (except for a few crashes).
