No need to repair, just do surgery, cut the nail bed, don't go to the people's hospital, and then usually pull it out for you, go to the municipal hospital or the affiliated hospital. I went to these two hospitals to have my hair cut, and the affiliated hospital sewed it, but the municipal hospital didn't sew it, so the affiliated hospital could see that it was afraid to come, and the municipal hospital couldn't see it. After the nail bed is cut, it no longer grows into the meat on both sides, but is vertical, so there will be no problem of paronychia once and for all.
