2. Perils of the pedicure 修脚会导致指甲感染
A pedicure may be relaxing - and a great way to get winter feet looking presentable again -- but an ingrown toenail will certainly stress you out. Germs picked up during a pedicure can lead to an ingrown toenail or an infection.

If that happens, don't go back to the salon, says Dr. Youner – see a podiatrist before it gets worse. A good rule of thumb is to choose a salon where the foot-soaking tub is either disposable or removable, says Dr. Youner, because a lot of infections may originate in the plumbing.

It can't hurt to bring your own tools, either – and even if they're yours, clean them before you head out. And when in doubt, apply some Bacitracin to your feet when you get home.
