The numbness of the skin or limb after the fracture must be judged according to the cause of the numbness before the length of the recovery time of the numbness can be judged. If the numbness occurs due to abnormal swelling of the limb after the fracture, and thus the swelling compresses the nerve of the limb, the numbness can be relieved soon after the swelling of the limb gradually subsides, and the symptoms can be gradually restored in about 1 week, or at the latest, not more than 2 weeks. However, if the nerve of the limb is injured by the fracture end, the recovery time is longer, and the recovery of the nerve must take 3 months at the earliest, and even more than 0.5-1 year in some cases.
