Understanding Knee Pain and Swelling

# Knee Pain That Swells After Minor Activity — Should I Get an MRI Scan?

## Why This Problem May Not Be Improving
Persistent knee pain with swelling after minor activities may indicate several underlying issues. Clinically possible reasons for continued discomfort may include:
• Structural injury not previously detected
• Disc or cartilage pathology
• Ligament or tendon injury
• Nerve compression
• Bone stress reactions
• Incomplete or imprecise diagnosis
• A plateau after conservative treatment
It is important to note that if symptoms persist beyond 6–12 weeks, further evaluation may be warranted.

## When Should an MRI Scan Be Considered?
An MRI scan may be considered in the following situations:
• Pain persists beyond 6–12 weeks
• Symptoms are worsening
• There is numbness, tingling, or weakness
• There is night pain
• There is recurrent swelling
• X-rays are normal but symptoms continue
• Conservative treatment has plateaued
• Diagnosis remains unclear
• Surgery is being considered
An MRI scan can provide detailed evaluation of important structures including:
• Discs
• Ligaments
• Tendons
• Cartilage
• Meniscus
• Labrum
• Nerve roots
• Bone marrow changes
It’s essential to clarify that an MRI scan is not always necessary but may be helpful when indicated.

## MRI Scan Safety
MRI scans are generally considered safe for most patients. Unlike X-rays or CT scans, an MRI scan:
• Does not use ionising radiation
• Uses magnetic fields and radiofrequency signals
• Is widely used for detailed soft tissue assessment
Patients will undergo safety screening prior to imaging to ensure appropriateness.

## Transparent MRI Scan Pricing (As of 1 March 2026)
