This is often the case with ear piercing, when the skin hasn't been looked after properly during the piercing or afterwards. Skin infections are painful and unsightly, quite the opposite of the desired effect of having the ear pierced. Many people are allergic to certain inexpensive metals, for example, nickel, which can also make the outside of the ear swell and feel uncomfortable. For this reason, pure metals, for example gold, are best used. Also follow the advice given for caring for the ear afterwards, so the chance of suffering problems is kept to a minimum.
Most people remember to protect their face.
Men forget the bald-patch on top of the head. But many people don't realise that the top of the ears are very exposed and sensitive to the sun's harmful UV rays. The solution is simple. Don't forget to protect them with sun protection cream and wear a hat that keeps them in the shade. Skin cancer can affect the ears too, and often does.
