If you've ever experienced tingling in your feet, burning sensations in your toes, unexplained numbness, or sharp nerve pain in the foot, you may have wondered whether it's simply poor circulation or something more.
These sensations are common peripheral neuropathy symptoms, yet many people dismiss them until they begin interfering with walking, sleeping, or daily activities. While neuropathy is often associated with diabetes, there are many other possible causes that deserve attention. As a Naturopathic Doctor practicing in Ontario for nearly two decades, I've found that one of the most important aspects of caring for people with peripheral neuropathy is taking the time to understand why it developed in the first place.
Rather than simply focusing on the symptoms, we investigate the underlying factors that may be contributing to nerve dysfunction so patients have a clearer understanding of their health.
Let's take a closer look at what peripheral neuropathy is, what causes it and the early warning signs you shouldn't ignore.
What Is Peripheral Neuropathy?
Peripheral neuropathy is a condition that occurs when the peripheral nerves become damaged or dysfunctional. These nerves connect your brain and spinal cord to the rest of your body, carrying messages that control movement, sensation and many automatic body functions. When these nerves are injured, those messages can become distorted, interrupted, or lost altogether.
The result can include:
- Tingling or "pins and needles"
- Burning sensations
- Numbness
- Sharp or electric-like pain
- Muscle weakness
- Changes in balance or coordination
Although neuropathy in feet is the most common presentation, the condition may also affect the hands, legs, arms, or other areas of the body.
What Is Neuropathy?
The term neuropathy simply means damage or disease affecting one or more nerves.
There are many different types depending on which nerves are involved:
- Sensory nerves (feeling)
- Motor nerves (movement)
- Autonomic nerves (heart rate, digestion, blood pressure, sweating)
Some people experience symptoms affecting only one type of nerve, while others develop more widespread nerve dysfunction. Because nerves influence virtually every system in the body, nerve problem symptoms can vary significantly from one individual to another.
Although diabetes is the leading peripheral neuropathy cause, many people develop nerve damage symptoms from vitamin deficiencies, thyroid disorders, autoimmune conditions, medication side effects, alcohol use, or nerve compression. Identifying the underlying cause is an important part of understanding what causes neuropathy in feet.
Peripheral Neuropathy Symptoms
One of the challenges with diagnosing peripheral neuropathy is that symptoms often develop gradually. Early neuropathy symptoms may seem mild or intermittent before becoming more persistent.
Common peripheral neuropathy symptoms include:
- Tingling in the toes or fingertips
- Burning sensations in the feet
- Numbness
- Increased sensitivity to touch
- Sharp shooting pain
- Nerve pain in the leg
- Nerve pain in foot
- Weakness in the ankles or hands
- Difficulty maintaining balance
- Feeling like you're wearing socks or gloves when you're not
Some individuals also notice symptoms worsening at night, making sleep difficult.
What Is the First Stage of Neuropathy?
Many people ask: What is the first stage of neuropathy?
The earliest stage is often characterized by subtle sensory changes.
These may include:
- Occasional tingling
- Mild numbness
- Intermittent burning
- Increased sensitivity
- A feeling that the feet are "different" without obvious pain
These symptoms often begin in the toes before gradually moving upward. Because early symptoms may come and go, people frequently delay seeking assessment until the condition has progressed. Recognizing these early warning signs can allow for earlier investigation into possible underlying causes.
What Causes Neuropathy in Feet?
The feet are often affected first because the nerves supplying them are the longest in the body, making them particularly vulnerable to damage over time. Some common peripheral neuropathy causes include:
Diabetes & Prediabetes
Chronically elevated blood sugar remains one of the leading causes of nerve damage worldwide. Interestingly, some people develop neuropathy even before receiving a diabetes diagnosis, making early awareness and access to diabetes treatment important.
Vitamin Deficiencies
Healthy nerves require adequate nutritional support. Deficiencies involving nutrients such as vitamin B12 or other essential vitamins may contribute to nerve dysfunction.
Thyroid Disorders
An underactive thyroid can sometimes contribute to symptoms including numbness, tingling, or muscle weakness.
Autoimmune Conditions
Certain autoimmune diseases may mistakenly attack peripheral nerves, resulting in inflammation and nerve injury.
Alcohol Use
Long-term excessive alcohol intake may contribute to both nutritional deficiencies and direct nerve damage.
Medication Side Effects
Some medications—including certain chemotherapy drugs—can affect nerve health.
Physical Compression
Pinched nerves, spinal disorders, repetitive strain injuries, or compression syndromes can produce localized neuropathy symptoms.
Infections
Certain viral or bacterial infections may affect peripheral nerves either directly or through immune system activation.
Idiopathic Neuropathy
In some cases, no single cause can be identified despite thorough investigation. This is known as idiopathic peripheral neuropathy.
What Is the Main Cause of Neuropathy?
If asked to identify the single most common cause, diabetes remains the leading contributor to peripheral neuropathy worldwide. However, it's important to recognize that diabetes is far from the only explanation. Many people experiencing foot neuropathy, neuropathy in hands, or nerve damage symptoms do not have diabetes. This is why a comprehensive assessment is so important. Identifying the underlying cause helps guide appropriate management and ensures potentially reversible contributors are not overlooked.
Neuropathy in Feet
The feet are usually affected before the hands.
People with neuropathy in feet commonly describe:
- Burning soles
- Tingling toes
- Reduced sensation
- Difficulty sensing temperature
- Feeling like they're walking on cotton or pebbles
- Increased risk of falls
Over time, reduced sensation may increase the likelihood of unnoticed cuts, blisters, or injuries.
Neuropathy in Hands
Although symptoms often begin in the feet, many people eventually develop neuropathy in hands as well.
Common symptoms include:
- Numb fingertips
- Difficulty buttoning clothing
- Reduced grip strength
- Burning fingers
- Dropping objects unexpectedly
These changes can interfere with daily activities and deserve medical evaluation.
Nerve Damage Symptoms That Shouldn't Be Ignored
Because nerves influence movement, sensation and many internal functions, nerve damage symptoms can extend beyond pain.
Seek assessment if you notice:
- Progressive numbness
- Increasing weakness
- Difficulty walking
- Loss of coordination
- Frequent falls
- Persistent burning pain
- Symptoms affecting both feet or both hands
- Changes in bladder or bowel function
- Rapidly worsening symptoms
Prompt evaluation helps identify serious underlying conditions that may require timely management.
How Naturopathic Doctors Approach Peripheral Neuropathy
As licensed primary care health professionals in Ontario, Naturopathic Doctors are trained to evaluate common medical conditions, order and interpret appropriate laboratory testing where indicated, perform physical examinations and recognize when referral or additional medical investigation is necessary.
Rather than viewing peripheral neuropathy as a diagnosis alone, we also ask an equally important question: Why has this nerve dysfunction developed?
A comprehensive assessment considers many factors that may influence nerve health, including metabolic function, nutritional status, endocrine health, digestive function, medication history, lifestyle factors, cardiovascular risk and other medical conditions. This whole-person perspective allows us to better understand both the symptoms someone is experiencing today and the factors that may have contributed to their development.
Persistent tingling, burning, numbness, nerve pain in foot, nerve pain in leg, or neuropathy in hands can be early signs of peripheral neuropathy. Early assessment can help identify the reason for these neuropathy symptoms before nerve damage progresses.
When Should You Seek Medical Evaluation?
Although occasional tingling may not always indicate a serious problem, persistent or worsening symptoms deserve attention.
If you experience:
- Ongoing numbness
- Burning pain
- Progressive weakness
- Loss of sensation
- Recurrent nerve pain in leg
- Persistent nerve pain in foot
it's worthwhile to have the problem evaluated sooner rather than later. Early assessment can help identify potentially reversible causes and may reduce the risk of further nerve injury.

Faq’s
What are the top three causes of peripheral neuropathy?
The three common causes are diabetes, long-term alcohol misuse and vitamin deficiencies, particularly vitamin B12 deficiency. Medications, autoimmune diseases, infections, kidney disease and injuries may also damage peripheral nerves.
What are the first signs of peripheral neuropathy?
Early signs include tingling, numbness, burning pain, pins-and-needles and increased sensitivity, usually beginning in the feet or hands. Some people also notice weakness or balance problems.
What organ is affected by neuropathy?
Neuropathy affects the peripheral nerves, not one specific organ. These nerves connect the brain and spinal cord to the skin, muscles and internal organs, so nerve damage can affect sensation, movement, digestion, blood pressure, or bladder function.
What vitamin deficiency causes neuropathy?
Vitamin B12 deficiency is a well-known cause of neuropathy and may cause numbness, tingling, weakness, or balance problems. Deficiencies in vitamins B1 and E may also contribute to nerve damage.
What are the five stages of peripheral neuropathy?
There is no universally accepted five-stage system. A common progression is: mild tingling, increasing pain, persistent numbness, muscle weakness or balance problems and advanced loss of sensation with complications such as falls or foot injuries.
The Bottom Line
Peripheral neuropathy is more than simply numb feet or occasional tingling. It represents a problem affecting the peripheral nervous system that may have many different underlying causes.
Whether symptoms involve foot neuropathy, neuropathy in hands, or unexplained nerve problem symptoms, they shouldn't simply be accepted as a normal part of aging. Understanding what is causing the nerve dysfunction is often the first step toward improving overall health. As a Naturopathic Doctor with nearly 20 years of experience providing primary care in Ontario, I believe one of the most valuable things we can do is carefully investigate both the symptoms and the factors contributing to them. Looking beneath the surface often provides important insights that help patients better understand their health and make informed decisions moving forward.
If you're experiencing ongoing peripheral neuropathy symptoms, a comprehensive assessment can help clarify what may be contributing to your symptoms and identify the next appropriate steps in your care.
