You want to get your cartilage pierced but you have to be able to participate in sports how can you keep your hole from closing?

If you can abstain for about a month you can switch the jewelry out to an easier to wear piece and then play. Another alternative is to have your cartilage dermal punched and a steel eyelet inserted and then in a month switch to a Kaos Softwear V.2.0 eyelet. Kaos eyelets are extremely comfortable and will squish with your ear instead of maintaining shape. Also, if you expect to have a lot of undo irritation then way until you are done with the sport for at least a year and then you should be able to remove the piercing for the event and put it in after the event.
