Peripheral Neuropathy Affects the Nerves Outside the Brain & Spinal Cord
Peripheral neuropathy refers to a broad group of conditions involving damage or dysfunction of the peripheral nerves. These nerves carry information between the brain and spinal cord and the rest of the body, including the feet, legs, hands, and arms.
Symptoms depend on which nerves are affected. Some people experience burning, electric or shooting pain, while others notice tingling, numbness, increased sensitivity, weakness, or difficulty sensing temperature or pain. Symptoms commonly affect the feet and legs and may also involve the hands and arms.
Understanding the Cause Is an Important Part of Neuropathy Care
Neuropathy is not a single disease with one cause. Diabetes is a common cause, but peripheral nerves can also be affected by physical injury, autoimmune conditions, infections, certain medications or toxins, nutritional deficiencies, inherited disorders, and other medical conditions. Sometimes the cause remains unknown even after evaluation.
That distinction matters because treatment should be guided by what is contributing to the nerve damage whenever the cause can be identified. At Innovative Medical Center, evaluation begins with your symptoms, medical history, previous diagnoses and treatments, and how the problem is affecting your function. The goal is to determine whether the services available at IMC may have an appropriate role in your care.
Neuropathy & Related Nerve Symptoms We Evaluate
Neuropathy symptoms can overlap with several other conditions. Burning, numbness, tingling, weakness, or pain in the feet does not automatically mean peripheral neuropathy, and determining where the symptoms originate can help guide the next step.
Depending on what you are experiencing, you may also want to learn more about:
- Diabetic Neuropathy – prolonged diabetes can damage peripheral nerves, particularly those affecting the feet and legs
- Pinched Nerves – localized nerve compression can also cause pain, numbness, tingling, or weakness but is different from peripheral neuropathy
- Sciatica – irritation involving the sciatic nerve pathway commonly produces symptoms extending from the lower back or buttock into one leg
- Back Pain – spinal conditions can sometimes produce neurological symptoms that resemble peripheral nerve problems
- Balance & Mobility Problems – loss of sensation or weakness associated with neuropathy can make walking and balance more difficult
- Foot Numbness & Burning – persistent changes in sensation deserve evaluation, particularly when symptoms are progressing or affecting both feet
For appropriate patients, IMC’s Neuropathy Care program may be considered based on the type of neuropathy, the severity of nerve involvement, contributing factors, and your overall health.
Frequently Asked Questions About Neuropathy
What is peripheral neuropathy?
Peripheral neuropathy refers to conditions in which nerves outside the brain and spinal cord become damaged or do not function properly.
These nerves carry sensory, motor, and other signals throughout the body. When they are damaged, symptoms may include pain, burning, numbness, tingling, weakness, or problems with balance and coordination.
What does neuropathy feel like?
Neuropathy can feel different from person to person.
Common sensations include:
- Burning
- Tingling or pins and needles
- Numbness
- Sharp or shooting pain
- Electric-like pain
- Increased sensitivity to touch
- Reduced ability to feel pain or temperature
- Weakness
Some people have significant pain, while others primarily notice loss of sensation.
Where does peripheral neuropathy usually start?
Many common forms of peripheral neuropathy begin in the feet or toes and may gradually extend upward into the legs. The hands can also become involved.
The pattern depends on the type of neuropathy and which nerves are affected.
What causes peripheral neuropathy?
Peripheral neuropathy has many possible causes.
These can include diabetes and other metabolic conditions, physical injury, autoimmune diseases, infections, exposure to certain medications or toxins, nutritional deficiencies, inherited conditions, and other diseases affecting peripheral nerves. In some people, an identifiable cause is not found.
Can diabetes cause neuropathy?
Yes.
Diabetes can damage peripheral nerves over time. Diabetic peripheral neuropathy commonly affects the feet and legs and may cause burning, shooting pain, tingling, numbness, weakness, or reduced ability to feel pain and temperature.
Is numbness in my feet always neuropathy?
No.
Foot numbness can have multiple possible causes. Peripheral neuropathy is one possibility, but nerve compression, spinal conditions, injuries, circulation problems, and other medical conditions can also produce changes in sensation.
Persistent, progressive, or unexplained numbness should be evaluated rather than assuming the cause.
Is neuropathy just poor circulation?
No.
Neuropathy and poor circulation are different problems, although a person can have both.
Peripheral neuropathy involves damage or dysfunction of nerves. Circulatory problems involve inadequate blood flow. Both can affect the feet and may produce symptoms that patients describe similarly, which is why an appropriate medical evaluation can be important.
Is neuropathy the same as a pinched nerve?
No.
Peripheral neuropathy generally refers to damage or dysfunction affecting peripheral nerves. A pinched nerve describes irritation or compression affecting a particular nerve or nerve root.
Both can produce numbness, tingling, burning, pain, or weakness, but the location, pattern, and underlying cause may be different.
Why is foot care important if I have diabetic neuropathy?
Loss of sensation can make it more difficult to notice cuts, blisters, pressure areas, or other injuries to the feet. For people with diabetes, these unnoticed injuries can develop into more serious foot problems.
Patients with diabetic neuropathy should follow the foot-care recommendations provided by their diabetes healthcare team.
When should numbness or tingling be evaluated?
Persistent, unexplained, recurring, or worsening numbness and tingling deserve medical evaluation, particularly when symptoms affect both feet or hands or begin to interfere with walking, balance, sleep, or daily activities.
Evaluation can help determine whether peripheral neuropathy or another nerve, spinal, metabolic, or medical condition may be contributing to the symptoms.
Can peripheral neuropathy be reversed?
Sometimes the underlying cause can be treated or controlled and symptoms may improve, but neuropathy is not universally reversible.
The outlook depends on what caused the nerve damage, which nerves are involved, how severe the damage is, and whether the underlying condition can be corrected or managed. Some neuropathies improve, while others can remain stable, progress, or leave lasting symptoms.
For that reason, IMC does not assume that every patient’s nerve damage can be reversed.
