The so called cauliflower ear occurs in people who train extensively almost every day. This deformation is caused by long periods of neglect and not resting when your ear is injured. It is not something which happens overnight, and there is usually plenty of time to take measures. These inflammations occur on different occasions: hard blows to the ear, friction and so on. We can guarantee proper prevention and safe training instructions in our beginner program. As an extra preventive measure, we can provide you with ear guards, which are designed to protect you from unwanted injury.
