Injuries happen, that’s a fact of life. You can do every single thing right, warm up properly, warm down, stretching, everything. Sooner or later, whether at training or in every day life, you will get an injury.
I’ve had my fair share, broken hands and fingers, broken shoulder, torn rotator cuff, dislocated shoulder, planta fasciitis, millions of leg corks from sparring, I even managed to accidentally cut my pinky finger off with a steak knife once.
Right now I’m dealing with a burst bursa sack, labrum tear and strained tendon in my shoulder from over training for my last fight. Through out all these injuries I still managed to get a decent amount of training in. With one arm essentially out of commission for the last 3 months I have taken the time I have to improve weaknesses in other areas, specifically my leg conditioning. Whenever I have had one leg out of commission my other leg has got so much stronger and when both legs are in working order again I have improved all around as an athlete. My arm was never the same after I dislocated it but since then instead of having an awesome left hook, I now have an average left hook that I always follow up with an awesome right. Adapt and overcome.
It may not seem like it at the time as mentally debilitating as injuries can be, they really can make you a better all around athlete in the long run, as long as they are not career ending obviously.
The main thing I see people doing incorrectly is not resting the injury when they should be. Most of the time when you do this you are re injuring an injury. Injuries don’t heal unless you rest them, give your body a chance to fix the problem. When it is time to start some light training on that body part again, just take it one step at a time, don’t get ahead of yourself and slowly, slowly build up to the capacity of which the injured area was once capable of. If you haven’t seen a doctor or a physio, you can’t know exactly what the problem is and therefore, what the correct recovery process is. Nothing is more important than your health, so spend the money and see the experts so you don’t risk turning a short term problem into a lifetime of pain and frustration.
