I've been practicing BJJ for quite some time now. Recently, in sparring sessions, I think I've hurt one of my ears. It pains a lot and now that ear has turned red. I've read in many sites that practicing BJJ can cause cauliflower ears. So, can someone help me with information to avoid cauliflower ears while practicing my regular classes.
A common precaution is to wear wrestling headgear, which is designed to protect the ears, while practicing. Cauliflower ear is caused by impacts or rubbing on the ear. Headgear will reduce both of these.
Ramsey Dewey had a video on this very topic that I thought was pretty good.
Essentially he thought that genetics played a large role in getting cauliflower ears. Regardless - you need to protect your ears.
