  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 1 in 50 Americans suffers from peripheral nerve damage. This type of damage becomes increasingly common with age. In one out of every  four people with diabetes has some nerve damage.
