![]() If the motor endplate receives no nerve impulse for more than 18-24 months, it dies away and there is no longer any way that the muscle can be activated by the nerve. The reason for this is a structure called the ‘motor endplate’, where the nerve joins into the muscle. Motor nerves have a time limit for healing. Sensory nerves are more resilient than motor nerves and can recover sensation months or years after injury. Some people notice continued improvement over many months. ![]() A nerve that is cut will grow at 1mm per day, after about a 4 week period of ‘rest’ following your injury. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. How long does my nerve take to regenerate? However, often the result is a lump of nerve ends (a neuroma) that is tender to knocks or pressure and in some cases can be uncomfortable all the time. If your nerve ends are not brought together, the nerve fibres still attempt to grow and find the other end. Recovery is improved if the cut nerve ends are brought together and repaired surgically. The extent to which your nerve will recover is variable, and it will always be incomplete. The nerve fibres (axons) shrink back and ‘rest’ for about a month then they begin to grow again. When one of your nerves is cut or damaged, it will try to repair itself. Damage to nerves may result in reduction or a complete loss of sensation, weakness and dry skin. Your nerves transmit sensory (feelings of touch, pressure or temperature) and motor (movement of muscles) impulses to and from your brain. Nerve Surgery & Nerve Repair - Information sheet
