Which are the symptoms of Peripheral Neuropathy?

Symptoms of Peripheral Neuropathy

Peripheral neuropathy refers to a condition that affects the peripheral nerves, which are responsible for transmitting signals between the central nervous system (brain and spinal cord) and the rest of the body. This condition can cause a wide range of symptoms, which can vary in severity and presentation depending on the underlying cause and the specific nerves affected. Here are some common symptoms associated with peripheral neuropathy:

Pain and Discomfort

Pain is one of the most common symptoms experienced by individuals with peripheral neuropathy. The pain can be described as sharp, shooting, burning, or tingling sensations. It may be localized to a specific area or may spread throughout the affected limbs. The intensity of the pain can range from mild to severe, and it may worsen at night.

Numbness and Tingling

Numbness and tingling sensations, also known as paresthesia, are frequently reported by individuals with peripheral neuropathy. These sensations can occur in the hands, feet, arms, or legs and may be constant or intermittent. The affected areas may feel "asleep" or have reduced sensitivity to touch, temperature, or pain.

Muscle Weakness and Atrophy

In some cases, peripheral neuropathy can lead to muscle weakness and atrophy. The affected muscles may become weaker over time, leading to difficulties with activities that require strength and coordination. Muscle atrophy refers to the wasting or shrinking of muscles due to lack of use or nerve damage.

Balance and Coordination Problems

Peripheral neuropathy can affect the sensory nerves responsible for providing feedback on balance and coordination. As a result, individuals may experience balance problems and difficulty coordinating movements. This can increase the risk of falls and impact daily activities.

Sensitivity to Touch

Some individuals with peripheral neuropathy may experience increased sensitivity to touch in the affected areas. Even light touch or pressure can cause discomfort or pain. This symptom is known as allodynia and can significantly impact the quality of life.

Autonomic Symptoms

Peripheral neuropathy can also affect the autonomic nerves, which control involuntary bodily functions. This can lead to various autonomic symptoms such as:

• Orthostatic hypotension: A sudden drop in blood pressure upon standing up, causing dizziness or lightheadedness.


• Gastrointestinal problems: Including nausea, vomiting, diarrhea, constipation, or difficulty swallowing.


• Urinary problems: Such as urinary incontinence, difficulty starting or stopping urination, or frequent urination.


• Sexual dysfunction: Including erectile dysfunction in men and vaginal dryness or difficulty achieving orgasm in women.


• Sweating abnormalities: Excessive sweating or lack of sweating.

Changes in Skin, Hair, and Nails

Peripheral neuropathy can also affect the skin, hair, and nails. Some individuals may experience changes in skin color or texture in the affected areas. The skin may become excessively dry, cracked, or prone to infections. Hair loss or abnormal hair growth and brittle or thickened nails can also occur.

Motor Symptoms

In addition to muscle weakness, peripheral neuropathy can cause various motor symptoms such as:

• Twitching or muscle cramps: Involuntary muscle contractions or spasms.


• Muscle fasciculations: Visible twitching or quivering of muscles.


• Muscle fatigue: A feeling of tiredness or weakness in the muscles, especially after minimal exertion.

It is important to note that the symptoms of peripheral neuropathy can vary greatly depending on the underlying cause, the specific nerves affected, and individual factors. Some individuals may experience a combination of these symptoms, while others may only have mild manifestations. If you suspect you may have peripheral neuropathy, it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate management.
