Take action:
Hold a pin with pliers and heat it till red hot; melt a small hole through the fingernail until the blood is released, which will quickly relieve the pain; no burning pain will be felt, as the fingernail contains no nerve endings; if the problem persists, repeat the procedure using the same hole. Apply an antibiotic ointment and cover the nail.
Blood under the fingernails
If a hand injury is limited to the fingertip, and the finger is not deformed or severely swollen, it is seldom necessary to visit the doctor. Apply an ice pack to reduce the swelling, and if blood clots under the fingernail, in can be removed in order to relieve pain and prevent possible infection.
