You know Dp I am a walking trainwreck ,they took bone marrow in large 4 inch holes in my hipps to make a bone in my leg .Yes I am handicaped by law but to ask the people I work with they say you could never tell .Broken arm many times with a replacement elbow .Broken ribs many times also a short stay in texas in traction for back injury ,dang plastic seats ha ha .So the glory of racing accidents is very jadded .But as your question of pain yes that is normal even at your age and if you smoke all detirmines how fast or if you heal .If you sit down and cry about your pain that is where you will stay .The best medicine is to keep on moving if it just breathing exercise keep going .You will forget the pain and you never know getting past the pain and adversity will take you .Sometimes it can make you a better man .
