cauliflower ear. You're already here at DSTRYR/sg, so there's no need for us to explain this common ailment/fashion statement. It's part of grappling, just like knee injuries and bouts with ring worm and the periodic staph infection (we'll talk about those on another occasion).
The funny thing about it - I've got some fairly normal looking ears despite 12.5 years of serious BJJ (and even another 4 years of HS wrestling). Call it luck or genetics, it doesn't really matter. Cauliflower happens and it happens frequently to a lot of grapplers.. I've seen fresh youngling white belts with less than 6 months of training with ears that resemble fried wontons.
This isn't a piece about how to deal with your cauliflower situation (for that, see). That answer is pretty clear - you're supposed to stop training and go see a doctor. That doctor will probably fix you up and then tell you not to train for a while. They always says that. And we (at least me) never listen and just get back on the mat for more training.
Or, you could do this (care of our buddies at Real Rio):
Note: We're not advising you or nor are we recommending you try this. If you have an ear problem, tell your mom and she'll take you to the doctor. Oh, and don't forget your blanky.
