Actually, pricking your ears is not very painful. It will pass in a minute. Don't be too nervous. The more nervous, the more painful.
After piercing your ears, you must pay attention to the hygiene of your ears Don't get wet, don't get infected, or it will be really painful.
If you really want to prick your ears, you'd better wait until April, around Tomb-Sweeping Day, because the weather at that time was more suitable for skin healing, so it's not good to prick your ears now, because it's easy to freeze your ears in cold weather, and then it's hard to maintain them.
