Peripheral neuropathy (PN) is a relatively common nerve disorder and presents as a challenge to more Indians than you think. It is a relatively common side effect associated with people with diabetes, Guillain Barre syndrome, vasculitis and those undergoing cancer treatment, where the peripheral nerves are either damaged or destroyed.
“I have a constant burning sensation in my hands. My feet feel like they’re asleep all the time. I can’t feel my toes. It’s like I’m walking on cotton balls. My feet feel like they’re on fire. The pain is like someone is stabbing me with needles.”
Dr Haripriya Kumaran (PT), Neuro physiotherapist at ReLiva Physiotherapy in Pune says, “Patients with neuropathic pain often report their symptoms like this! These only indicate that the nerves are not sending the signals properly.”
This article has been written to increase understanding about peripheral neuropathy. By recognising the early symptoms and knowing what are the warning signs of peripheral neuropathy and reporting these to the doctor, action can be taken. This may reduce the severity or progression of the symptoms, and prevent the possibility of irreversible nerve damage.

What is Peripheral Neuropathy?
‘Peripheral’ means ‘situated away from the centre’ and refers to the outer areas of the body. ‘Neuropathy’ means ‘disease or malfunction of the nerves’.
In simple words, Peripheral neuropathy (PN) is a general term for nerve damage that occurs outside the brain and spinal cord. Due to the damage, the brain either does not receive signals or may receive the wrong signal. For example, the brain may not get a pain signal when something is hurting. Or it may receive pain signals when there is nothing that leads to pain.
PN can affect any part of the body, but most commonly affects the hands and feet.
Symptoms of Peripheral Neuropathy
Peripheral neuropathy can cause a variety of symptoms, including:
- Numbness, tingling, or burning sensation in the hands or feet
- General weakness
- Increased sensitivity to touch causing pain (neuropathic pain)
- Balance problems
- Difficulty walking
- Decreased reflexes
- May also affect vision, hearing, bladder movement
Peripheral Neuropathy and its Incidence in India
The incidence of PN varies depending on the specific cause and the population studied. In India, the reported prevalence ranges widely, from 5 to 2,400 per 10,000 population. A medical study [1] reports, India’s vast population encompasses various ethnicities and lifestyles, potentially impacting PN risk factors.
Causes of Peripheral Neuropathy
- Multiple causes: Numerous factors can cause PN, including diabetes, infections like leprosy, vitamin deficiencies, autoimmune diseases, and exposure to toxins.
- Diabetic neuropathy (DPN): A major contributor, with studies suggesting a prevalence of 10% to 90% in diabetic patients. This wide range reflects diverse populations and diagnostic methods.
- Other causes: Leprosy neuropathy, though declining due to control programs, remains a concern. Vitamin B12 deficiency, common in India, can also contribute.
- Urban vs. rural: Studies suggest higher PN rates in urban areas, potentially due to lifestyle factors and increased exposure to toxins.
Types of Peripheral Neuropathy
Peripheral neuropathy disease can be classified into different types based on the affected nerves and the extent of damage.
Types of Peripheral Neuropathy, by the extent of nerves affected:
1. Mononeuropathy:
When only a single nerve is affected, resulting in localized symptoms in the area supplied by that nerve.
Common causes of Mono neuropathy include compression, trauma, and infections.
Carpal tunnel syndrome is an example of Mononeuropathy, where the median nerve in the wrist is affected, causing numbness and tingling in the hand and thumb.
2. Polyneuropathy:
When a condition affects multiple nerves throughout the body, often causing symmetrical symptoms in the hands and feet, it is named as Polyneuropathy. This may be caused by various conditions, including diabetes, autoimmune diseases, vitamin deficiencies, and toxins.
Diabetic neuropathy is the most common type of peripheral neuropathy that is also polyneuropathic. It can cause burning pain, numbness, and weakness in the legs and feet.
Types of Peripheral Neuropathy, by which type of nerves are affected:
Nerves that can be affected by peripheral neuropathy are the motor (that which controls muscle movements), sensory (that which controls sensations) or autonomic (that which controls automated functions in the body such as blood pressure or bowel movements).
1. Motor Neuropathy:
When the motor nerves are affected, it leads to muscle weakness, wasting, and difficulty in moving. This can be caused by various conditions, including autoimmune diseases, toxins, and inherited disorders.
Example: Guillain-Barré syndrome, an autoimmune disorder that attacks the motor nerves, causing rapid muscle weakness and paralysis.
2. Sensory Neuropathy:
The sensory nerves control sensations. When they are affected, it leads to symptoms like numbness, tingling, burning pain, and difficulty feeling temperature or pain. This can be caused by various conditions, including diabetes, vitamin deficiencies, and infections.
Example: Small fiber neuropathy, a type of sensory neuropathy that affects the small nerve fibers responsible for pain, temperature, and autonomic functions.
3. Autonomic Neuropathy:
The autonomic nerves control involuntary functions like heart rate, blood pressure, digestion, and bladder function. When they get affected, it is named as autonomic neuropathy. This often causes symptoms like dizziness, lightheadedness, sexual dysfunction, and difficulty controlling body temperature. This may be caused by various conditions, including diabetes, Parkinson’s disease, and autoimmune diseases.
Treatment for Neuropathy in Legs and Feet: How is neuropathic pain treated?
Peripheral Neuropathy Treatments
Doctors prescribe the medicine according to the need. It might be topical or oral medications. Vitamins supplements, hormones, pain relievers with anti-depressants are different options to treat neuropathic pain.
In addition to medicines, other treatment may be required to help you manage other symptoms.
For example, if you have muscle weakness, and problem with balance and walking you may need physio therapy for neuropathy to learn exercises to improve your muscle strength. TENS therapy may also help in reduction of pain.
You may also need to wear splints to support weak ankles or use walking aids to help you get around.
Physiotherapy is most beneficial for Peripheral Neuropathy to achieve the following outcomes:
- Reduced pain and discomfort
- Improved muscle strength and function
- Enhanced balance and gait
- Increased flexibility and range of motion
- Improved quality of life
- Reduced risk of falls and complications

Who can benefit with Physiotherapy for Peripheral Neuropathy?
Research suggests that physiotherapy can be a valuable component of managing Neuropathy, though its efficacy can differ depending on the specific type and cause.
Physio therapy for neuropathy has been found to be especially helpful for patients with conditions, namely:
- Diabetic Neuropathy: Research suggests physiotherapy based exercise programs, can effectively improve pain, balance, and walking ability in people with diabetic neuropathy. This includes strengthening, aerobic, and flexibility exercises.
- Sciatica: Physiotherapy is often the first-line treatment for sciatica, focusing on manual therapy, core strengthening, and stretching to relieve pain and improve mobility.
- Carpal Tunnel Syndrome: Physiotherapy can help manage carpal tunnel symptoms through nerve glides, stretches, and splinting to reduce pressure on the median nerve.
- Foot Drop & Wrist Drop: Physiotherapy, splinting and exercises have been established as most effective mode of conservative treatment. Stretching exercise is required to improve the patient’s way of walking, range of motion of the knee/ wrist and strengthen the surrounding muscle, increase balance, and posture and reduce fear and risk of falling.
- Chemotherapy-Induced Peripheral Neuropathy: Studies suggest exercise programs in patients with chemotherapy-induced neuropathy can offer moderate pain relief and improve muscle strength. Transcutaneous electrical nerve stimulation (TENS) therapy can sometimes help reduce pain by delivering tiny electrical impulses to specific nerve pathways at or near the site of pain.
