Peripheral Nerve Conditions
Peripheral Nerve conditions occur when nerves are squeezed or compressed, leading to pain, numbness, tingling, and weakness. These conditions can affect nerves in the spine, skull base, or peripheral nerves throughout the body. While often starting as minor nuisances, untreated nerve compression can lead to permanent nerve damage and disability.
Dr Joseph Garcia Redmond provides evaluation and treatment of nerve compression syndromes affecting the brain, spine, and peripheral nervous system. His comprehensive neurosurgical training, including fellowship training in skull base surgery at Toronto Western Hospital, enables him to manage complex nerve compression conditions using both conservative and surgical approaches.
Dr Garcia Redmond's approach emphasises accurate diagnosis, attempting conservative management when appropriate, and offering surgical treatment when necessary to prevent permanent nerve damage and restore function. He works closely with pain specialists and rehabilitation teams to ensure comprehensive care.
What is Peripheral Nerve Compression?
Nerve compression syndromes occur when pressure is applied to a nerve, disrupting its normal function. Compression can result from bone spurs, herniated discs, tumors, swelling, scarring, or anatomical abnormalities. The specific symptoms depend on which nerve is affected and the severity of compression.
Common Peripheral Nerve Compression Syndromes:
Cranial Nerve Compression Syndromes
Trigeminal Neuralgia: Compression of the trigeminal nerve (5th cranial nerve), typically by a blood vessel pressing against the nerve at the brain stem. Causes sudden, severe facial pain.
Hemifacial Spasm: Compression of the facial nerve (7th cranial nerve), usually by a blood vessel, causing involuntary twitching of facial muscles on one side.
Glossopharyngeal Neuralgia: Rare compression of the glossopharyngeal nerve (9th cranial nerve) causing severe pain in the throat, tongue, ear, and tonsil area.
Spinal Nerve Compression Syndromes
Cervical Radiculopathy: Compression of nerve roots in the neck, typically from herniated discs or bone spurs, causing pain, numbness, and weakness radiating into the arms and hands.
Lumbar Radiculopathy (Sciatica): Compression of nerve roots in the lower back, causing pain radiating down the leg, often accompanied by numbness and weakness.
Spinal Stenosis: Narrowing of the spinal canal compressing the spinal cord (cervical stenosis/myelopathy) or nerve roots (lumbar stenosis), causing pain, weakness, and walking difficulties.
Cauda Equina Syndrome: Severe compression of the bundle of nerves at the bottom of the spinal cord, a surgical emergency requiring immediate treatment.
Peripheral Nerve Compression Syndromes
Carpal Tunnel Syndrome: Compression of the median nerve at the wrist, causing hand numbness, tingling, and weakness (though typically treated by hand surgeons or orthopedic surgeons, neurosurgeons may be consulted for complex cases).
Cubital Tunnel Syndrome: Compression of the ulnar nerve at the elbow, causing numbness in the ring and little fingers and hand weakness.
Peroneal Nerve Compression: Compression of the peroneal nerve at the knee, causing foot drop and numbness on top of the foot.
Meralgia Paresthetica: Compression of the lateral femoral cutaneous nerve, causing numbness and burning sensation on the outer thigh.

What are the Symptoms of Peripheral Nerve Compression?
Symptoms vary depending on which nerve is compressed and the severity of compression, but may include:
Pain that may be sharp, burning, or aching
Sudden, severe, shock-like or stabbing pain
Numbness or tingling in the area supplied by the affected nerve
Weakness of specific muscles
Episodes lasting seconds to minutes
Pain-free intervals between attacks (initially, though may become more constant over time)
Involuntary twitching or spasms (especially on the face: Hemifacial Spasm)
Balance problems, clumsiness, difficulty walking,
Bowel or bladder problems and sexual dysfunction in severe cases
Muscle wasting in severe, chronic cases
When to Seek Immediate Medical Attention:
Seek emergency care if you experience:
Sudden loss of bladder or bowel control
Numbness in the saddle area
Severe weakness in both legs
Progressive weakness in any limb
Symptoms of spinal cord compression (difficulty walking, hand clumsiness, balance problems)
These could indicate serious nerve compression requiring urgent surgical treatment.
How is Peripheral Nerve Compression Diagnosed?
Clinical Assessment: Dr Garcia Redmond will take a detailed history of your symptoms, and will undertake a neurological examination to identify which nerve is affected, including provocative tests (specific manoeuvres that reproduce symptoms) and the Assessment of muscle strength, sensation, and reflexes.
Imaging Studies:
MRI scan: High-resolution imaging to visualise nerve-vessel contact. Best imaging for herniated discs, spinal stenosis, nerve root compression.
Thin-slice MRI: Detailed visualisation of cranial nerves and surrounding structures
CT scan: Visualizes bone anatomy, useful for bony stenosis
X-rays: Assess spinal alignment and degenerative changes
CT myelogram: Special imaging when MRI cannot be performed
Electrodiagnostic Studies:
EMG (Electromyography): Tests muscle electrical activity
Nerve Conduction Studies: Measures how well nerves transmit electrical signals
Useful for confirming peripheral nerve compression and assessing severity
Dr Garcia Redmond will review all diagnostic information with you and explain how the findings relate to your symptoms.
How Do You Treat Peripheral Nerve Compression?
Treatment depends on the specific syndrome, severity, duration of symptoms, and presence of neurological deficits.
Conservative (Non-Surgical) Treatment Options
Medications: Including anti-inflammatory medications, pain medications, muscle relaxants
Physical Therapy: Particularly helpful for spinal nerve compression, strengthening and stretching exercises, postural training, manual therapy techniques.
Activity Modification: Avoiding positions or activities that worsen symptoms, ergonomic adjustments, weight loss if appropriate.
Pain Management Injections: Epidural steroid injections, Selective nerve root blocks or Trigger point injections.
Bracing: Cervical collars or lumbar supports (short-term use) to reduce nerve irritation.
Conservative treatment is often successful for mild to moderate nerve compression, particularly when symptoms are recent. However, surgery may be necessary when conservative treatment fails or when there's progressive weakness or severe compression.
Surgical Treatment Options
Microvascular Decompression (MVD): a neurosurgical procedure to treat conditions like trigeminal neuralgia, glossopharyngeal neuralgia, and hemifacial spasm by relieving pressure on a cranial nerve caused by a blood vessel.
Nerve Decompression/Release: Surgical release of compressed nerves (such as ulnar nerve transposition for cubital tunnel syndrome). Can be performed as minimally invasive procedure in many cases.
Gamma Knife Radiosurgery: Focused radiation is delivered to the trigeminal nerve to reduce pain signals.
Other Procedures: Percutaneous procedures (radiofrequency, balloon compression, glycerol injection) may be offered by pain specialists for patients not suitable for MVD or Gamma Knife.
Muscle Relaxants Injections: Temporary relief of spasms (3-4 months), may be used while awaiting surgery or for patients not wanting surgery.
Microdiscectomy: Minimally invasive removal of herniated disc material compressing a nerve root. Small incision, muscle-sparing approach, typically outpatient or overnight stay.
Foraminotomy: Enlargement of the opening where nerve roots exit the spine, relieving compression from bone spurs or disc material.
Spinal Fusion: May be added to decompression if instability is present or if significant bone removal is required. Joins vertebrae together to provide stability.
Dr Garcia Redmond will discuss the most appropriate treatment approach for your specific nerve compression syndrome, considering severity, duration, your health, and treatment goals.
Your Recovery and Aftercare
Recovery varies significantly depending on the specific procedure and nerve involved. Dr Garcia Redmond and his team will support you throughout your recovery journey.
After Microvascular Decompression (Cranial Nerves): Typically 2-3 days hospital stay. Most patients experience immediate or rapid pain relief (within days). Full recovery: 6-12 weeks. Long-lasting results in most patients.
After Gamma Knife for Trigeminal Neuralgia: Same-day discharge from hospital, and you will be able to resume normal activities within 1-2 days. Pain relief develops gradually over 2-8 weeks (sometimes longer).
After Spinal Decompression Surgery: Hospital stay ranges from same-day discharge to 2-3 days depending on procedure complexity. Many patients notice immediate relief of radiating pain. Full recovery: 3-6 months.
Rehabilitation: Physical therapy typically begins a few weeks after surgery to strengthen muscles, improve flexibility, and optimize function.
Follow-Up Care: Regular follow-up appointments are essential to monitor recovery. This might include clinical examinations to assess symptom resolution and neurological function, wound checks to ensure proper healing, imaging if needed to confirm adequate decompression, guidance on activity progression and return to work and management of any persistent symptoms.
Ongoing Treatment: Some patients require continued pain management (usually much reduced after successful surgery), physical therapy for strengthening and flexibility, monitoring for recurrent compression (can occur years later with continued degenerative changes).

Most nerve compression surgeries have high success rates with low complication rates when performed by experienced neurosurgeons. Dr Garcia Redmond will discuss your individual risk profile based on your specific condition.
Will nerve compression get better on its own?
Some mild nerve compression, particularly from disc herniations, can improve spontaneously with conservative treatment over weeks to months. However, severe or progressive nerve compression, especially with weakness, often requires surgical intervention. Chronic compression can lead to permanent nerve damage. If symptoms persist beyond 6-12 weeks despite conservative treatment, or if weakness develops, surgical evaluation is important.
How do you know if nerve damage is permanent?
Permanent nerve damage is indicated by persistent, severe weakness that doesn't improve despite treatment, marked muscle atrophy (wasting), and complete loss of sensation. Electrodiagnostic studies (EMG/nerve conduction) can help assess the degree of nerve damage. The longer compression persists, the higher the risk of permanent damage. This is why prompt treatment of severe compression is crucial.
What is the success rate for trigeminal neuralgia surgery?
Microvascular decompression has an 80-90% success rate for immediate pain relief, with most patients remaining pain-free for many years. About 10-20% experience pain recurrence over time, which can often be successfully retreated. Gamma Knife radiosurgery achieves pain relief in 70-80% of patients, though relief develops more gradually. Success rates are highest when surgery is performed earlier in the disease course.
Can sciatica be cured?
Many cases of sciatica from disc herniation resolve with conservative treatment over 6-12 weeks. For persistent or severe sciatica, microdiscectomy surgery has an 85-95% success rate for leg pain relief. However, sciatica can potentially recur if further disc material herniates or if degenerative changes progress. Maintaining core strength, proper body mechanics, and healthy weight helps reduce recurrence risk.
How long does it take for a compressed nerve to heal after surgery?
Pain relief from nerve decompression is often rapid (days to weeks), as pressure is removed. However, recovery of sensation and strength depends on how long the nerve was compressed and the severity of damage. Mild compression may recover in weeks, while severe chronic compression may take months or may not fully recover. Nerve regeneration occurs slowly (roughly 1mm per day), so recovery from severe nerve damage can take many months.
Is microvascular decompression major surgery?
While MVD involves craniotomy (opening the skull), modern neurosurgical techniques make this a relatively safe procedure. Most patients stay in hospital 2-3 days and recover within 6-8 weeks. Serious complications are rare in experienced hands. The surgery is performed through a small opening behind the ear and uses microsurgical techniques to carefully move blood vessels away from the nerve without damaging delicate structures.
Can nerve compression cause permanent paralysis?
Severe, untreated spinal cord compression (myelopathy) or cauda equina syndrome can cause permanent paralysis if not treated promptly. Single nerve root compression rarely causes complete paralysis but can cause significant weakness. This is why emergency symptoms (loss of bladder/bowel control, progressive weakness, severe spinal cord compression) require immediate surgical treatment to prevent irreversible damage.
Are there exercises that help nerve compression?
Physical therapy exercises can be very helpful for spinal nerve compression, particularly for improving posture, strengthening core muscles, and reducing pressure on nerves. Specific stretches may also help. However, exercises should be guided by professionals, as some movements can worsen compression. For cranial nerve compression (trigeminal neuralgia, hemifacial spasm), exercises are generally not beneficial as these are caused by vascular compression at the brain stem.
Will I need to take medications forever after surgery?
Most patients who undergo successful surgery for nerve compression can discontinue or significantly reduce medications. After microvascular decompression for trigeminal neuralgia, medications are typically tapered off over weeks to months. After spinal decompression, pain medications can usually be stopped once healing is complete. Some patients continue neuropathic pain medications for residual symptoms, though typically at lower doses.
