What is a pinched nerve?

A pinched nerve, also called nerve compression or entrapment, occurs when increased pressure on a nerve results in irritation, inflammation and damage to the nerve. This pressure usually comes from surrounding tissues, such as bones, cartilage, muscles or tendons. When a nerve is “pinched” in this manner, it can cause pain, numbness, tingling and weakness along the path of the nerve.

Some common examples of pinched nerves include:

Carpal tunnel syndrome – Compression of the median nerve as it travels through the wrist into the hand.
Sciatica – Compression of the sciatic nerve as it travels from the lower back through the buttocks and down the leg.
Ulnar nerve entrapment – Compression of the ulnar nerve as it travels from the neck down into the hand.

Pinched nerves can occur in many areas of the body. They often arise due to injury, poor posture, repetitive motions, obesity, arthritis and other medical conditions that cause inflammation or structural abnormalities. Aging and normal “wear and tear” of the tissues can also contribute to pinched nerves over time.

What causes a pinched nerve?

Some common causes and risk factors for a pinched nerve include:

Bone spurs – Extra bone growth that presses on a nerve.

Herniated discs – Ruptured or bulging discs that protrude and compress nerves in the spine.
Swollen tendons – Thickened or inflamed tendons that narrow the space available for nerves.
Arthritis – Inflammation and degeneration can cause bone and joint changes that pinch nerves.

Injuries – Broken bones, dislocated joints, scar tissue formation.
Pregnancy – Weight gain, inflammation and posture changes can pinch nerves.
Diabetes – Nerve damage (neuropathy) makes nerves more susceptible to compression.

Repeated motions – Repetitive injury and muscle strain creates inflammation.
Poor posture – Slouching and improper form compresses nerves.
Obesity – Extra weight compresses nerves.

In many cases, there are structural or physiological issues contributing to nerve compression. However, even maintaining good posture and performing nerve “gliding” exercises can help take pressure off pinched nerves in some instances.

Symptoms of a pinched nerve

Symptoms of a pinched nerve depend on the location of the affected nerve and which functions it controls. Common symptoms include:

Sharp, shooting or burning pain

Numbness or tingling
Muscle weakness
Difficulty moving the affected area

“Pins and needles” sensations
Loss of coordination or balance

For example, a pinched nerve in the neck can cause shoulder and arm pain, numbness in the hand, or weakness in the muscles of the arm and hand. A pinched nerve in the lower back can radiate pain down the leg, cause numbness in the foot, or lead to leg muscle weakness.

The onset of symptoms is often gradual, beginning with some mild tingling or soreness that worsens over time. Symptoms may come and go at first but become more constant as the nerve compression increases.

Diagnosing a pinched nerve

To diagnose a pinched nerve, a doctor will begin with a physical exam, inspecting for areas of tenderness, muscle weakness, reduced reflexes and changes in sensation along the path of the affected nerve. They may also order tests such as:

X-rays – Views of the bones around nerves can reveal arthritis, bone spurs, fractures or other issues.

MRI – This imagery can pinpoint herniated discs, tumors, muscle swelling and other masses pressing on nerves.
Nerve conduction study – Small electrodes measure how well electricity travels along a nerve.
Electromyography – Records the electrical signals of muscle fibers.

These tests can help confirm that nerve compression is occurring and determine the exact location. This allows targeting treatment to the appropriate area.

How long does it take for a pinched nerve to heal?

The timeline for recovery depends on the nerve affected and severity of the compression:

Mild compression may heal within a few days to weeks with rest and conservative treatment.

Moderate cases can take 2-3 months to improve as swelling resolves.
Severe pinching with significant inflammation can take 6 months or longer to heal.
Chronic compression that has been present for an extended time is slower to recover.

Healing also depends on the underlying cause. If a structural problem like a herniated disc or bone spur is pinching the nerve, healing cannot complete until that issue is corrected.

With mild injuries, resting the area and avoiding aggravating activities may be enough for the tissues swelling around the nerve to subside. But severe or long-standing cases often require medical treatment or surgical intervention for complete resolution.

Treating a pinched nerve

Treatment focuses on relieving pressure on the nerve and reducing inflammation. Options may include:

NSAIDS – Anti-inflammatory medications like ibuprofen to reduce swelling.
Ice/heat – Icing reduces inflammation while heat eases muscle tension.
Immobilization – Braces, splints or casts restrict movement to allow healing.

Physical therapy – Stretches and exercises bring circulation to calm nerve irritation.
Steroid injections – Directly inject corticosteroids around an inflamed nerve.
Surgery – Procedures like decompression surgery or removing bone spurs.

In most cases, pinched nerves gradually improve with conservative treatment like rest, ice, NSAIDs and physical therapy. But if the nerve compression is severe or caused by an underlying medical condition, surgery may be recommended.

Can a pinched nerve be permanent?

In most cases, pinched nerves are not permanent if appropriately treated. The outlook is good, especially when caught early before substantial nerve damage occurs.

However, a pinched nerve can become permanent and lead to lifelong symptoms if:

The nerve compression is left untreated for an extended period.
There is significant tissue damage or scarring around the nerve.
An underlying condition like diabetes or autoimmune disease is present.

The cause cannot be corrected, such as an inoperable tumor or severe structural defect.
Muscle atrophy or loss of sensation has already occurred.

The longer a pinched nerve remains compressed, the higher the chances of permanent nerve injury. Seeking prompt medical treatment is key to preventing permanent symptoms.

Signs a pinched nerve may be permanent

Some signs that a pinched nerve may be permanent or have caused lasting nerve damage include:

No improvement in symptoms after 6 months of appropriate treatment.
Visible muscle wasting in the area supplied by the nerve.

Loss of sensation that does not begin to recover.
Persistent numbness or paralysis in the extremity.
No reflexes when tested by a neurological exam.

A chronic and irreparable underlying cause, like severe spinal arthritis.

If muscle wasting, loss of reflexes, paralysis or severe sensory changes occur, it indicates the nerve has suffered significant damage. The nerve fibers themselves may have developed scar tissue that blocks their function. At this point, the changes are often permanent even if the compression is corrected.

Preventing pinched nerve damage

You can reduce the chances of a pinched nerve becoming permanently damaged by:

Seeking prompt treatment at the first signs of symptoms.
Avoiding activities that aggravate symptoms.
Using proper posture and ergonomics at work and home.

Keeping inflammation down with ice, NSAIDs, compression.
Getting physical therapy to improve range of motion.
Maintaining a healthy weight to avoid compressing nerves.

Treating medical conditions that can contribute to nerve compression.

While not always possible to prevent a pinched nerve, these steps can help avoid activities making it worse and allow the nerve time to heal before permanent damage sets in. Getting any underlying structural problems or chronic illnesses under control also reduces the risk.

Finding symptom relief for a pinched nerve

Depending on the location, finding relief from a pinched nerve often requires:

Resting the affected area to avoid aggravating activities.
Ice packs can help reduce inflammation around the compressed nerve.
Over-the-counter NSAIDs (aspirin, ibuprofen, naproxen) decrease swelling.

Elevating the area above heart level aids drainage of fluid buildup.
Braces or splints immobilize and take pressure off the area.
Physical therapy provides nerve gliding and range of motion exercises.

Massage therapy helps relax muscles putting pressure on nerves.
Chiropractic adjustments can re-align the spine and joints compressing nerves.
Corticosteroid injections block inflammation around irritated nerves.

Surgery may be required for structural causes or severe entrapment.

Seeking professional treatment can help determine if time and conservative care will relieve the pinched nerve or if surgical intervention is required.

What’s the outlook for pinched nerve recovery?

The majority of pinched nerves improve significantly with proper treatment and time:

Mild pinching often resolves within a few weeks.
Moderate cases may take 2-3 months to see improvement.
Severe compression can take 6 months or longer for inflammation to resolve.

Surgery to correct underlying structural causes speeds recovery.
Physical therapy helps regain flexibility and strength of affected muscles.
Good ergonomics and posture can prevent recurrence.

The sooner treatment begins after onset of symptoms, the better the outlook. Permanent nerve damage is unlikely if appropriate medical care starts quickly. However, delaying too long increases the risks of a pinched nerve becoming a chronic problem.

When to see a doctor for a pinched nerve

You should consult a doctor promptly if you experience:

Intense or worsening numbness, tingling, pain, weakness in an extremity.

Loss of sensation or inability to move the affected area.
No improvement in symptoms after a few weeks of self-care.
Difficulty with urination or bowel movements.

Muscle wasting or loss of reflexes upon examination.

Seeking urgent medical care can help prevent permanent damage if a nerve is severely pinched or compressed. Diagnostic tests can determine the exact location and cause of the nerve entrapment. Early treatment may speed recovery before complications develop.

Conclusion

Pinched nerves are relatively common but can cause debilitating symptoms. With appropriate rest, physical therapy, anti-inflammatory medications and other treatments, most resolve without permanent nerve injury. However, delaying too long increases the risks of lasting nerve damage. Seeking prompt medical attention is crucial, especially if muscle wasting, numbness or weakness occur. Getting the underlying cause addressed, whether bone spurs, herniated discs or something else, helps decompress the nerve and restore function. Proper ergonomics and posture can also help prevent recurrence. While some cases of pinched nerves do cause lifelong impacts if severe enough, most people make a full recovery by following through with their recommended treatment plan.
