Nail shedding
No matter whether the nail falls off or is injured, as long as the nail bed exists, the nail can regenerate. Measures must be taken immediately to disinfect and stop bleeding, and then go to the hospital to see a doctor. Although the fallen nails will not reattach to the fingers, it is best to hold down the fallen nails to effectively compress and stop bleeding.
Bleeding blister
The first measure that must be taken immediately is to apply cold compress to the injured part. If the finger can't move as usual, it may be that the tendon near the nail is broken, so you should go to the hospital immediately to see a doctor.
Nail injury
Don't peel off your nails if they haven't completely fallen off. If the blood bubble is not too painful, you can leave it alone. With the growth of new nails, blood bubbles will naturally disappear. Nail injuries can lead to carbuncle. When the nails are injured or the skin is injured due to ingrown nails, bacteria will enter the wound and cause suppuration. Purulent under the nail or at the edge of the nail is called carbuncle. Most carbuncles have severe pain and should be treated in hospital before they fester.
Matters needing attention
Restore the bare nails to their original positions, press them with gauze, wrap them tightly with tape or bandage, and send them to hospital for treatment. Cooling the affected area with a cold towel so that the fingers are at the same height as the heart can relieve the pain.
