Nerve recovery usually takes about 3-6 months. Nerve compression can be followed by edema, which needs to be addressed first, and special dehydrating medications need to be used to relieve nerve edema. After nerve compression, regional numbness may develop for a short period of time. At this time, oral methylcobalamin is needed to treat and nourish the nerves, and at the same time, appropriate activities are given to the affected limbs to promote the transmission of brain waves to the limbs through the nerves, which is also conducive to the recovery of the nerves. If the nerve is fractured or damaged, surgical anastomosis is needed to repair the nerve and the outer membrane of the nerve, and it takes about 3-6 months to recover from such a situation, and after recovery, the distal end of the limb may have numbness, because the nerve is a non-renewable cell.
