Normal MRI but Still in Pain? Reasons Scans Don’t Always Explain Symptoms

I’ve Been Told My MRI Is Normal — Why Am I Still in Pain?

It can feel confusing and sometimes invalidating to be in real pain while being told your scans are “normal”. MRI and other imaging tests are valuable, but they are not a complete explanation for persistent pain. This article explains why scans may not give a clear answer, why some findings are incidental, and how we interpret imaging properly by matching it to your symptoms and examination findings.

Key message

We treat the patient, not the MRI. Scans are one part of the assessment and only become meaningful when they match your symptoms, examination findings, and how the pain behaves.

Why a “normal” MRI can happen even when pain is real

MRI is excellent at showing structure such as bones, discs, nerves, joints, and soft tissues. However, pain is not only about structure — it is also about how nerves and the nervous system process signals.

Some pain sources do not show clearly on scans, especially when the problem is functional rather than a clear structural injury.

Facet joints and the sacroiliac (SI) joint commonly show degenerative (“wear and tear”) changes on MRI, but these findings are very common in people without pain and do not reliably confirm that the joint is the source of symptoms.

Examples of pain that may not be clearly explained by MRI: facet joint pain, mechanical SI joint pain, myofascial pain, ligament or tendon-related pain, nerve sensitisation, and some neuropathic pain conditions.

Imaging shows anatomy — but anatomy doesn’t always equal symptoms

A scan can tell us what a disc or joint looks like, but it cannot always tell us whether it is the true cause of your pain.

This is why we look for clinical correlation, meaning scan findings must match the symptom pattern, physical examination, and pain behaviour.

A scan finding is only meaningful if it explains your pain.

Incidental findings: a normal part of ageing

Many people have disc bulges, degenerative changes, or mild narrowing on MRI even if they have no pain at all.

These are called incidental findings — changes seen on scans that may not be responsible for symptoms.

Chasing incidental findings can lead to unnecessary treatments and missed diagnoses.

When MRI findings do matter

MRI findings are most helpful when they clearly match the clinical picture.

• Disc prolapse with nerve root contact matching radiating arm or leg pain.
• Spinal stenosis matching walking-related leg pain relieved by sitting.
• Facet degeneration matching back-dominant pain worsened by extension or rotation.

Dermatomes and pain patterns

A dermatome is an area of skin supplied by a specific nerve root from the spine.

If a nerve root is irritated, symptoms often follow a recognisable pattern of pain, tingling, or numbness.

In real life, pain does not always follow textbook diagrams perfectly, which is why dermatomes are used as a guide alongside examination and clinical judgement.

Does scan positioning matter?

Most MRI scans are performed lying down and are appropriate for assessing discs, nerves, and soft tissue structures.

Some symptoms are mainly triggered by standing or walking. In these cases, standing or dynamic X-rays may provide more useful information.

MRI and X-rays answer different clinical questions and are used together.

Which scan is best — and when?

• MRI: discs, nerves, soft tissues.
• Standing X-rays: alignment and load-related change.
• Dynamic X-rays: suspected instability.
• Diagnostic injections: confirmation of pain source.

Important note: Standing MRI is rarely required in routine practice.

How Pain Spa can help

At Pain Spa, we take a detailed, stepwise approach to persistent pain, focusing on identifying the most likely pain generators rather than relying on scan findings alone.

Dr Krishna has extensive experience in assessing complex pain conditions and performing targeted, image-guided diagnostic and therapeutic procedures.

If your MRI is “normal” but pain persists, a specialist assessment can help clarify the diagnosis and guide appropriate treatment. Please contact Pain Spa at clinic@painspa.co.uk or via our website www.painspa.co.uk. to arrange a consultation.
