Peripheral Neuropathy
Peripheral neuropathy is a condition that occurs when nerves outside of the brain and spinal cord become damaged or dysfunctional. These nerves, known as peripheral nerves, play a crucial role in transmitting signals between the body and the brain, controlling sensation, movement, and other functions.
​
Peripheral neuropathy can manifest in various ways, depending on the types of nerves affected and the extent of the damage. Common symptoms of peripheral neuropathy may include:
-
Tingling or Numbness: Many people with peripheral neuropathy experience tingling, numbness, or a sensation of pins and needles in the affected areas. This sensation can occur in the hands, feet, arms, or legs.
-
Burning or Sharp Pain: Some individuals may experience burning, stabbing, or shooting pain in the affected areas. The pain may be constant or intermittent and can range from mild to severe.
-
Loss of Sensation: Peripheral neuropathy can lead to a loss of sensation in the affected areas, making it difficult to feel touch, temperature, or pain. This loss of sensation can increase the risk of injury or infection.
-
Muscle Weakness or Wasting: In some cases, peripheral neuropathy can cause muscle weakness, twitching, or atrophy (wasting). This can lead to difficulty with movement, coordination, and balance.
-
Changes in Reflexes: Peripheral neuropathy can affect reflexes, leading to abnormal reflex responses when tested by a healthcare provider.
-
Sensitivity to Touch or Temperature: Some individuals may experience increased sensitivity to touch, temperature, or pressure in the affected areas, known as hyperesthesia or allodynia.
-
Autonomic Symptoms: In addition to sensory and motor symptoms, peripheral neuropathy can affect the autonomic nervous system, leading to symptoms such as changes in blood pressure, heart rate, digestion, and sweating.

Peripheral neuropathy can have various causes, including diabetes, infections, autoimmune disorders, genetic factors, trauma or injury, exposure to toxins, and certain medications. Treatment for peripheral neuropathy focuses on managing symptoms, addressing the underlying cause when possible, and preventing complications such as injuries and infections.
