Never had to try and fix broken ribs but was on the receiving side of one broken rib and one cracked rib on the left side of my chest on my side. Montana Golden Gloves tournament can do that to a guy. (Many years ago.) Got the ribs broken in a semifinal bout which I won with a young man from Billings Montana. Tough son of a gun. I won the fight but about an hour after and my adrenaline dumped oh man did it hurt. Hurt to laugh, ride in a car. Went to the ER since I was supposed to fight the net night in the championships to see if I could do it or not. Doctor never took any x-rays and just told me that I had some really bruised ribs and he suggested I not fight again for 2-3 weeks. Hey the championship bout was a fellow from Canada who was a 5 time Canadian national champion and won a bronze medal in the 1976 Olympic Games. Hell yeah I'm going to fight him. I had been training for that fight all year long knowing that Canada was coming down to our tournament.
Needles to say the next night even warming up shadow boxing and hitting mitts was Painful! Went out there the first round and he had watched my prior bout where I got my ribs clobbered. He went right to work on them. About half way through the first round he hit me with a good shot to the rigs and my gloves dropped. You could tell I was hurt and the ref gave me a standing 8 count. Yep I'm fine lets go. Went another minute or so and he stuck me again on my left side below my heart. Crap the gloves dropped again and it hurt. Another 8 count. Yep I'm fine ref, lets go! Just about through the first round and he tagged me a hellish shot to the ribs again and this time it dropped me to my knees. Three 8 counts in one round and the ref automatically stops the fight.
Summation: Broken ribs are serious and they hurt like nobodies business especially after the adrenaline goes away. Still a neat honor I felt getting to fight one of the best amateur fighters in the world.
