I was accidentally squeezed into my finger by fitness equipment when I was exercising the afternoon before yesterday! It hurts! It hurts! At that time, fingernails were all purple! Now the fingernails are all black. It's too late to see your question. It's nothing. When I sent this to you, you should have stopped hurting. It usually hurts for two or three days, three or four days at most, and then it doesn't hurt. But usually it is best to wrap it with a thin cloth or emery cloth, and it is best not to use a band-aid. Because the band-aid is airtight, new nails will fall off. After two months, the new nails will fall off completely. According to my experience of losing my nails more than seven or eight times, you are now the most painful time, but just don't think about it and don't touch it. It doesn't really hurt that much. I have toenails now, just like you now, and I still insist on running five kilometers every day. It hurts a little, but today, and then it will be fine.
