Pinching a finger is one of the most common injuries, especially during childhood. Even in the mildest case, the victim experiences severe pain. However, this is not the worst thing in this situation. Lack of medical examination and untimely assistance can lead to serious consequences.
After pinching the finger, edema often appears, and if the blood vessels are damaged, a hematoma. First aid is to cool the tissues. Run your finger under cold running water. In the absence of serious damage, pronounced edema will subside within an hour, while the pain will subside at the same time.
If this does not happen, apply a dry bandage to the injured finger and often apply ice wrapped in cellophane or thick cloth. Try not to wiggle your injured limb again. For pain relief, take an analgesic, for example, "Baralgin", "Nurofen", etc. Observe the dynamics for two days. If there is improvement, replace the cold compresses with warm ones, and use heparin ointment for the speedy resorption of the hematoma. If there is no improvement or if the mobility of the finger is impaired, see a traumatologist and take an X-ray. Bone damage is likely the cause of severe pain and swelling. Also, this may be indicated by an increase in body temperature and deformation of the finger.
Often, when a finger is pinched, a violation of the integrity of the nail plate occurs. But this is not always evidenced by a crack. Sometimes a red spot forms under the nail, which can grow and turn black over time. If the damage is significant, it will save months, it will go away, gradually being replaced by a new one. It is important to keep your hands clean to avoid introducing infection into the wound. In addition, care must be taken not to further injure the injured finger.
If you experience any discomfort caused by old toenail coming off, see your doctor. A specialist under local anesthesia will remove the damaged nail plate and tell you what to do to heal quickly and painlessly.
