Nerve Weakness: Causes, Symptoms and Treatment Options

Nerve weakness, also known as neuropathy, refers to a condition where nerves do not work properly, often resulting in symptoms such as muscle weakness, numbness, tingling, and pain. This condition can arise from various causes, including injuries, infections, autoimmune diseases, and vitamin deficiencies.

Causes of Nerve Weakness

Diseases, injuries, infections, and limb loss are some of the common causes of nerve weakness or neuropathic pain.

Disease

Neuropathic pain may be a symptom or complication of a variety of diseases and conditions, including associated with neuropathic pain:

Multiple sclerosis
Pancreatic cancer
Autoimmune diseases
Arthritis in the Spine
Diabetes
Thyroid Syndrome

Not everyone with these conditions experiences neuropathic pain.

Diabetic individuals often experience:

Loss of feeling and numbness
Pain, burning, and stinging in the limbs

Injuries

Injuries to tissues, muscles, or joints are a rare cause of neuropathic pain.
Back, leg injuries, and severe arthritis can sometimes lead to long-lasting nerve damage.
Even after the injury heals, the nervous system may still be affected, causing ongoing issues.
This can result in chronic pain that persists for months after the original injury.

Infections

Infections are rarely a cause of neuropathic pain.
Shingles, caused by the reactivation of the chickenpox virus, can lead to neuropathic pain.
This pain may occur along the affected nerve and can last for several weeks.
A major form of shingles-related pain is postherpetic neuralgia, which involves persistent neuropathic pain even after the rash heals.

Limb Loss

Phantom limb syndrome is a rare type of neuropathic pain.
It can occur after an arm or leg has been amputated.
Even though the limb is no longer there, the central nervous system still expects pain signals from the missing body part.
As a result, the person may feel pain, itching, or other sensations where the limb used to be.

Other causes of Nerve Pain

Vitamin B deficiency
Chronic alcohol use
Carpal Tunnel syndrome
Facial Nerve Problems
Repetitive strain injuries

If you’re experiencing nerve-related pain or weakness, consult our Neurology Specialists for accurate diagnosis and advanced treatment options.

Symptoms of Nerve Weakness

Some of the severe symptoms of Nerve Pain are:

Shooting, burning or stabbing pain
Tingling and numbness (Pins and needles)
Spontaneous pain, or pain that occurs without a trigger
Evoked pain or pain which is caused by events which is not typically not painful
The chronic sensation of feeling unpleasant or abnormal
Difficulty in sleeping or resting
Chronic pain and loss of sleep

When to See a Doctor

You should see a doctor if you notice:

Sudden or severe muscle weakness
Numbness or tingling that doesn't go away
Weakness that worsens over time
Difficulty walking, holding objects, or doing daily tasks
Changes in bladder or bowel control

Diagnosis of Nerve Weakness

Doctors use different tests to find the cause of nerve weakness. These may include:

Physical exam: To check muscle strength, reflexes, and coordination.
Blood tests: To find vitamin deficiencies or infections.
Electromyography (EMG): Checks how well your muscles respond to nerve signals.
Nerve conduction studies: Measures how fast electrical signals move through your nerves.
MRI or CT scan: To check for pressure on nerves or brain/spinal cord issues.

Accurate testing under our Neurology Department helps identify the source of nerve damage and plan the right course of treatment.

Treatment of Nerve Weakness

The goal of neuropathic pain therapy is to:

Recognize and, if possible, address the underlying disease or condition responsible for the pain.
Relieve your discomfort.
Help you maintain typical capacities despite your pain.
Significantly improve your quality of life.

Common Treatment Options

The most frequent treatments for neuropathic pain, when effective, can bring a sense of relief and hope. These include:

Pain medication

Nonsteroidal anti-inflammatory drugs (NSAIDs) like Aleve and Motrin are commonly used to treat general pain.
These medications may be prescribed for nerve pain in some cases.
However, doctors often do not recommend NSAIDs for nerve weakness, as they are not effective in addressing the root cause.
NSAIDs do not target the specific source of nerve-related pain or damage.
Proper diagnosis and treatment are needed for effective relief from nerve weakness and related symptoms.

Prescription Medication

Opioid medications reduce nerve pain as well as various types of pains. Sometimes, the doctor may feel hesitate as the person may become dependent for a while.

Lifestyle Therapies

Physical therapy, massage, and relaxation techniques are all used to relieve the symptoms and improve mobility of neuropathic pain. Your health professional can also teach you how to deal with your pain.

For example, some people with neuropathic pain may experience increased symptoms after sitting for a few hours. This could make desk work difficult to control. Physiotherapist or occupational therapists can teach you sitting, stretching, standing and moving techniques to prevent pain.

Tips to Prevent Nerve Weakness

While some causes of nerve weakness can't be prevented, these steps may help:

Eat a balanced diet with enough vitamins (especially B vitamins)
Avoid alcohol and smoking
Manage chronic conditions like diabetes
Exercise regularly to maintain nerve and muscle health
Protect yourself from injuries and repetitive strain

How to Strengthen Weak Nerves

Provide the nerves with the supplies they need to transmit messages

The nerve needs minerals, proteins, and vitamins to send electrical impulses. The nutrients that should be consumed:

Dark Chocolate is rich in tryptophan, an amino acid that also acts as a neurotransmitter a substance that transmits a signal from one nerve to another.
Calcium and Potassium. These minerals regulate the electrical impulses produced and transmitted by nerves. If blood vessels are left to fire off uncontrolled impulses, a person may suffer from epilepsy or other nervous disorders.
Bananas, oranges, pomegranates, and prunes are good sources of potassium, while milk, leafy greens, and eggs are rich sources of calcium.
Vitamin B Vitamin B1, B2 , and B6 help the nerves to send impulses from the brain to the body.

Protect the Nerves with vitamin B

Every nerve has a protective covering called the myelin sheath, which works like insulation for efficient nerve signal transmission.
Damage to the myelin sheath is linked to neurological diseases such as Alzheimer's.
Maintaining adequate levels of vitamin B12 is important for keeping the myelin sheath healthy.
Good food sources of vitamin B12 include beef, poultry, eggs, and seafood.
Folate, a type of B vitamin, also helps protect nerves and supports overall nerve health.

Pursue well-being to improve the health of the Nerves

Exercise can help improve the function of nerves that control muscles and other parts of the body.
Physical activity stimulates the nervous system, which helps strengthen nerves in a similar way to how exercise strengthens muscles.
Herbal teas, like green tea, may help boost the production of serotonin and dopamine, which are important for mood and nerve function.

Use yoga and stretching to strengthen the nervous system

When the body is under stress from work, relationships, or travel, it produces high levels of cortisol, a stress hormone.
Continuous production of cortisol can negatively affect the central nervous system, impacting reflexes, memory, and concentration.
Yoga plays a vital role in stress management by promoting relaxation and muscle release.
Yoga also helps activate the part of the central nervous system that controls breathing and heart rate, supporting overall mental and physical well-being.

Your health is everything - prioritize your well-being today.

Conclusion

Neuropathic pain or nerve pain can have a negative impact on your life if you do not take steps to treat it and prevent the symptoms from getting worse. Over time, this can lead to serious disability and complications, including depression, sleeping problems, anxiety, and more.
