Understanding Nerve Compression on an MRI: Symptoms & Next Steps

What Does It Mean When Your MRI Shows Nerve Compression?

If you’ve been told that your MRI shows nerve compression, you’re likely wondering what that means for your health and what you should do next. Nerve compression can lead to pain, numbness, tingling, or weakness and is often linked to conditions like sciatica, spinal stenosis, and radiculopathy.

At Read My MRI, we help you decode your MRI report so you can fully understand your condition and take the right next steps toward relief.

What is Nerve Compression?

Nerve compression occurs when a nerve is pinched, squeezed, or irritated by surrounding tissues. This can happen due to:

  • Herniated discs pressing on nerve roots

  • Bone spurs from arthritis narrowing nerve pathways

  • Spinal stenosis, which reduces space for nerves in the spinal canal

  • Degenerative disc disease, causing reduced cushioning between vertebrae

An MRI is one of the most effective imaging tools to confirm nerve compression and identify its underlying cause.

Common Conditions That Cause Nerve Compression on MRI

1. Sciatica (Lumbar Radiculopathy)

🔹 What it is: Sciatica occurs when the sciatic nerve in the lower back is compressed, often by a herniated disc or bone spur.

🔹 Symptoms:

  • Sharp, shooting pain down one leg

  • Numbness or tingling in the lower back, buttocks, or leg

  • Muscle weakness in the affected leg

🔹 What MRI Shows:

  • Disc herniation pressing on the L4, L5, or S1 nerve roots

  • Narrowing of the spinal canal (stenosis)

  • Inflammation around the affected nerve

2. Cervical Radiculopathy (Pinched Nerve in the Neck)

🔹 What it is: Compression of a nerve in the neck (cervical spine) can cause pain that radiates down the arm.

🔹 Symptoms:

  • Neck pain that spreads to the shoulders and arms

  • Numbness or tingling in the hands and fingers

  • Weakness when gripping or lifting objects

🔹 What MRI Shows:

  • Herniated disc or bone spur at C5-C6 or C6-C7

  • Nerve root inflammation or compression

  • Spinal stenosis causing narrowing of nerve exit points

3. Spinal Stenosis

🔹 What it is: A condition where the spinal canal narrows, putting pressure on the spinal cord and nerves.

🔹 Symptoms:

  • Pain or heaviness in the legs, especially when walking

  • Numbness, tingling, or weakness in the lower body

  • Relief when sitting or bending forward

🔹 What MRI Shows:

  • Narrowing of the spinal canal, often in the lumbar spine

  • Thickened ligaments pressing on nerves

  • Disc bulges reducing space for nerves

4. Herniated Disc

🔹 What it is: When the soft, gel-like center of a spinal disc pushes out and compresses a nearby nerve.

🔹 Symptoms:

  • Localized or radiating pain

  • Numbness or tingling along the affected nerve path

  • Weakness in the arms or legs

🔹 What MRI Shows:

  • Disc protrusion pressing on a specific nerve root

  • Inflammation and swelling around the nerve

What to Do if Your MRI Shows Nerve Compression

If your MRI confirms nerve compression, the next step is determining the best treatment. Here’s what you can do:

Step 1: Understand Your MRI Report

Your report may include nerve root compression, foraminal narrowing, or impingement, but what do they mean for your symptoms?

👉 Use Read My MRI’s AI-powered service to translate your MRI findings into simple, easy-to-understand language.

Step 2: Consider Conservative Treatments First

Many cases of nerve compression do not require surgery. Non-invasive options include:

  • Physical therapy to strengthen muscles and relieve pressure

  • Chiropractic care or spinal decompression therapy

Step 3: Know When to Seek Surgery

If symptoms persist or worsen despite treatment, surgery may be an option. Common procedures include:

  • Microdiscectomy (for herniated discs)

  • Laminectomy (to relieve spinal stenosis)

  • Spinal fusion (in severe instability cases)

A second opinion can help confirm if surgery is truly necessary.

Step 4: Get an Overread on Your MRI

Not sure if your MRI results have been interpreted correctly? An overread may:

  • Confirm whether nerve compression is truly present

  • Identify any overlooked findings

  • Offer a clearer path forward for treatment

Read My MRI provides expert-reviewed, AI-assisted MRI interpretations so you can make the best health decisions.

If your MRI shows nerve compression, don’t panic. Understanding what’s causing your symptoms is the first step toward relief. Whether you’re dealing with sciatica, radiculopathy, or spinal stenosis, having the right information empowers you to take control of your health.
