If your nerve is healing properly, you may not need surgery. You may need to rest the affected area until it's healed. Nerves recover slowly, and maximal recovery may take many months or several years.
How long damaged nerves take to heal is variable, depending on the type of injury and where along the nerve the injury occurs. Peripheral nerves regenerate and heal at approximately 1 mm/day.
With peripheral neuropathy, it can be the other way around: once the cause is removed or at least reined in, the nerves may heal. and the symptoms ease up. Peripheral neuropathy from diabetes is a prime example.
Schwann cells can help damaged nerves regenerate and restore function. On average, damaged nerves can grow back at a rate of about 1 inch per month or 1 millimeter per day. Surgery is needed if there is significant scar tissue or a gap between cut nerve ends.
Peripheral nerves are fragile and easily damaged. A nerve injury can affect the brain's ability to communicate with muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy. It's important to get medical care for a peripheral nerve injury as soon as possible.
During the healing time, you might have pain or “pins and needles” sensation along the course of the nerve. You may need therapy to help keep your joints moving and your pain controlled while your nerve is growing. If it has been a long time since your nerve damage, nerve repair may not be possible.
Peripheral neuropathy happens when the nerves that are located outside of the brain and spinal cord (peripheral nerves) are damaged. This condition often causes weakness, numbness and pain, usually in the hands and feet. It also can affect other areas and body functions including digestion and urination.
Once the insulating cover of the nerve is repaired, the nerve generally begins to heal 3 or 4 weeks after the injury. Nerves usually grow 1 inch every month, depending on the patient's age and other factors.
First degree: A reversible local conduction block at the site of the injury. This injury does not require surgical intervention and usually will recover within a matter of hours to a few weeks. Second degree: There is a loss of continuity of the axons (the “electrical wires”) within the nerve.
When a peripheral nerve is damaged, the body cleans up the damaged tissue. Then damaged axons may regrow, beginning at the end nearest the brain. In time they may grow enough to re-establish a connection and allow the nerve to work again.
