How to heal nerve damage in leg

Nerve damage is commonly thought of as a complication of diabetes, but it can also result after an injury. Nerve damage is also known as peripheral neuropathy. The nerves that are most likely to be damaged tend to be in your arms, feet, and hands, although other parts of the body may also be affected.

When you’re injured or have surgery, the nerves no longer get the signal from your brain to transmit sensation. Sometimes, nerves that are only partially damaged can heal themselves. Dr. Jonathan Shults at Coastal Empire Orthopedics offers this guide to help you recognize the warning signs of nerve damage and the next steps you should take. 

How nerve damage happens

Nerve damage can occur after any injury, with the results often being related to the severity of the injury. Minor injuries may cause some nerve damage, but your body tries to heal itself whenever possible. However, more serious injuries can cause severe nerve damage which often requires nerve repairs. 

Nerves are made up of fibers, which are also called axons. These fibers are covered with tissues that act as a type of insulation. Sometimes, after an injury, only the fibers are damaged. In the more serious scenarios, both the fibers and tissues are damaged. In some cases, the nerve is completely cut.

The signs of nerve damage

Without properly functioning nerves, you are likely to experience uncomfortable or even painful sensations. These occur because the nerves are not able to carry the correct signals from the brain to the spinal cord. The signs of nerve damage include the following:

  • Numbness or tingling in the hands and feet
  • Feeling like you’re wearing a tight glove or sock
  • Muscle weakness, especially in your arms or legs
  • Regularly dropping objects that you’re holding
  • Sharp pains in your hands, arms, legs, or feet
  • A buzzing sensation that feels like a mild electrical shock

Nerve damage tends to be worse in the part of the body that was injured. For example, if you injured your arm or shoulder, you may have more symptoms in your arms and hands than in your feet.

Repairing nerve damage 

Damaged nerves can sometimes be repaired, especially if they are treated quickly after an injury. For that reason, it’s important to call us after a serious injury or when you first notice the signs of nerve damage. This is a situation in which you don’t want to wait too long because sometimes nerves reach a point of being irreparable. 

Dr. Shults can repair nerves, whether or not you’ve caught the symptoms early enough. He explores the damaged nerve(s) and removes any injured tissues. Then, he can often reconnect even severed nerves, as long as there’s enough of the nerves left to reattach without making it too tight.

Once the nerve has been repaired, you can generally expect sensation to come back gradually over a period of a couple of months. Your nerves have an ability to heal and regenerate even once they have been damaged, assuming that they have been properly repaired.

If you suspect you have nerve damage, it’s important to come see us right away. Treatment is available and nerve damage isn’t something you have to learn to accept. Call our Savannah office at 912-225-4888 or request an appointment online. 

Your nervous system is involved in everything your body does, from regulating your breathing to controlling your muscles and sensing heat and cold.

There are three types of nerves in the body:

  1. Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.
  2. Motor nerves. These nerves control your movements and actions by passing information from your brain and spinal cord to your muscles.
  3. Sensory nerves. These nerves relay information from your skin and muscles back to your spinal cord and brain. The information is then processed to let you feel pain and other sensations.

Because nerves are essential to all you do, nerve pain and damage can seriously affect your quality of life.

What Are the Symptoms of Nerve Pain and Nerve Damage?

With nerve damage there can be a wide array of symptoms. Which ones you may have depends on the location and type of nerves that are affected. Damage can occur to nerves in your brain and spinal cord. It can also occur in the peripheral nerves, which are located throughout the rest of your body.

Autonomic nerve damage may produce the following symptoms:

  • Inability to sense chest pain, such as angina or heart attack
  • Too much sweating (known as hyperhidrosis) or too little sweating (known as anhidrosis)
  • Lightheadedness
  • Dry eyes and mouth
  • Constipation
  • Bladder dysfunction
  • Sexual dysfunction

Damage to motor nerves may produce the following symptoms:

  • Weakness
  • Muscle atrophy
  • Twitching, also known as fasciculation
  • Paralysis

Sensory nerve damage may produce the following symptoms:

  • Pain
  • Sensitivity
  • Numbness
  • Tingling or prickling
  • Burning
  • Problems with positional awareness

In some instances, people with nerve damage will have symptoms that indicate damage to two, or even three, different types of nerves. For instance, you might experience weakness and burning of your legs at the same time.

What Causes Nerve Pain and Nerve Damage?

There are more than 100 different types of nerve damage. The various types may have different symptoms and may require different types of treatment.

It is estimated that about 20 million Americans suffer from peripheral nerve damage. This type of damage becomes increasingly common with age. Up to 70% of people with diabetes have some nerve damage.

While not an exhaustive list, the following are some of the possible causes of nerve pain and nerve damage:

  • Autoimmune diseases. A variety of different types of autoimmune diseases can produce symptoms of nerve pain and nerve damage. These include: multiple sclerosis, Guillain-Barré syndrome (a rare condition in which the immune system attacks the peripheral nerves), lupus, and inflammatory bowel disease.
  • Cancer. Cancer can cause nerve pain and nerve damage in multiple ways. In some instances, cancerous masses may push against or crush nerves. In other cases, certain types of cancer may result in nutritional deficiencies that affect nerve function. Additionally, some types of chemotherapy and radiation may produce nerve pain and nerve damage in certain individuals.
  • Compression/trauma. Anything that results in trauma or compression of nerves can result in nerve pain and nerve damage. This includes pinched nerves in the neck, crush injuries, and carpal tunnel syndrome. Learn more about pinched (compressed) nerves.
  • Diabetes. Up to 70% of people with diabetes suffer from nerve damage, which becomes more likely as the disease progresses. Diabetic neuropathy is a serious complication and may affect all three types of neurons. Sensory nerves are most often affected, causing burning or numbness. If you have diabetes and are experiencing symptoms of nerve pain or nerve damage, you should consult a medical professional as soon as possible. Take this assessment to see if you're at risk for diabetic nerve pain.
  • Drug side effects and toxic substances. Various substances that are taken into the body intentionally or unintentionally have the ability to cause nerve pain and nerve damage. These include medications, such as some chemotherapies for cancer and certain drugs used to treat HIV. Chronic alcohol use is a common cause of nerve pain and nerve damage. Toxic substances that may be ingested accidentally, including lead, arsenic, and mercury, may also cause damage to your nerves. Learn about other side effects of certain medications.
  • Motor neuron diseases. The motor neurons are nerves in your brain and spinal column that communicate with the muscles throughout your body. Diseases that affect these nerves, including amyotrophic lateral sclerosis, also called ALS or Lou Gehrig's disease, can result in progressively worsening nerve damage. Read more on the different types of motor neuron diseases.
  • Nutritional deficiencies. Deficiencies of certain nutrients, including vitamins B6 and B12, may produce symptoms of nerve pain and nerve damage, including weakness or burning sensations. Nutritional deficiencies that cause nerve damage may also result from excessive alcohol ingestion or develop after gastric surgery. See a list of food sources of vitamins and minerals.
  • Infectious disease. Certain infectious diseases have the ability to affect the nerves in your body. These conditions include Lyme disease, the herpes viruses, HIV, and hepatitis C. View a slideshow on the most common infectious diseases in the U.S.

How Are Nerve Pain and Nerve Damage Treated?

In many instances, nerve damage cannot be cured entirely. But there are various treatments that can reduce your symptoms. Because nerve damage is often progressive, it is important to consult with a doctor when you first notice symptoms. That way you can reduce the likelihood of permanent damage.

Often, the first goal of treatment is to address the underlying condition that's causing your nerve pain or nerve damage. This may mean:

  • Regulating blood sugar levels for people with diabetes
  • Correcting nutritional deficiencies
  • Changing medications when drugs are causing nerve damage
  • Physical therapy or surgery to address compression or trauma to nerves
  • Medications to treat autoimmune conditions

Additionally, your doctor may prescribe medications aimed at minimizing the nerve pain you are feeling. These may include:

  • Pain relievers
  • Tricyclic antidepressants such as amitriptyline and desipramine (Norpramin), as well as other antidepressants, including duloxetine (Cymbalta) and venlafaxine (Effexor XR)
  • Certain anti-seizure drugs, including neurontin (Gabapentin) pregabalin (Lyrica)
  • Capsaicin cream

Complementary and alternative approaches may also help alleviate your nerve pain and discomfort. These include:

  • Acupuncture
  • Biofeedback
  • Hypnosis
  • Meditation
  • Antioxidant vitamins
  • Electrical nerve stimulation such as TENS

How long do damaged leg nerves take to heal?

Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of 'rest' following your injury.

Can nerve damage in leg be cured?

In many instances, nerve damage cannot be cured entirely. But there are various treatments that can reduce your symptoms. Because nerve damage is often progressive, it is important to consult with a doctor when you first notice symptoms. That way you can reduce the likelihood of permanent damage.

How do you fix nerve damage in legs naturally?

Walk it off. Exercise releases natural painkillers called endorphins. Exercise also promotes blood flow to the nerves in the legs and feet. Researchers believe that regular exercise may create a long-lasting expansion in blood vessels in the feet, nourishing damaged nerves back to health.

What is the best way to repair nerve damage?

Peripheral nerve injuries can be treated nonoperatively with rest, physical therapy, desensitization techniques and medications to numb the pain while allowing the nerve to grow back.
