Paronychia can be treated in any hospital, not in the quality of doctors, but in hospitals. Mainly pay attention to more maintenance at ordinary times, and often disinfect with iodine, like before going to bed. Don't let your nails stand next to the meat, they will fester. The only way to fester is to pull out your nails ... and pay attention to cutting your nails often, but don't cut them too deep. If your nails are too deep, they may stick to the meat during the long closing process.
