Actually, it's not that much trouble I just nailed a nail today. Please find a master with good manicure skills, and let him push his nails to the roots with a nail clipper, and then infer that he will come out with a little prick. It hurts a little, but it's much easier than pulling nails. After pushing, everyone should pay attention to disinfection and ventilation, so as not to get wet. Cut off the small thorn as soon as it grows. I have never heard of a cure for this disease. Remember to ask him to disinfect the nail pushing equipment.
