Persistent Numbness in Arm After Treatment — Should an MRI Scan Be Done?

Persistent numbness in the arm after treatment can be a concerning symptom for many individuals. Understanding the underlying causes and when to consider further imaging, such as an MRI scan, is essential for appropriate management. This article will explore the potential reasons for ongoing numbness, the role of MRI scans in diagnosing these issues, and guidance on when to seek additional medical advice.

Key Takeaways

• Persistent numbness in the arm can have various underlying causes that require thorough evaluation.
• Conditions such as nerve compression, injury, or systemic issues may lead to chronic numbness.
• MRI scans can help identify structural problems contributing to persistent arm numbness.
• Patients should consider factors like duration and severity of symptoms when deciding on an MRI.
• Consulting a healthcare professional is essential for proper diagnosis and treatment options.

Understanding Persistent Numbness in the Arm

# Persistent Numbness in Arm After Treatment — Should an MRI Scan Be Done?

## Why This Problem May Not Be Improving
Persistent numbness in the arm after treatment may be attributed to various clinically possible reasons, including:
• Structural injury not previously detected
• Disc or cartilage pathology
• Ligament or tendon injury
• Nerve compression
• Bone stress reactions
• Incomplete or imprecise diagnosis
• Plateau after conservative treatment
Symptoms that continue beyond 6–12 weeks may warrant further evaluation to identify the underlying cause of the numbness.

## When Should an MRI Scan Be Considered?
An MRI scan may be considered if:
• Pain or numbness persists beyond 6–12 weeks
• Symptoms are worsening
• There are signs of numbness, tingling, or weakness
• There is night pain
• There is recurrent swelling
• Previous X-rays show normal findings but symptoms continue
• Conservative treatment has plateaued
• The overall diagnosis remains unclear
• Surgery is being considered
An MRI scan provides detailed evaluation of various structures, including discs, ligaments, tendons, cartilage, nerve roots, and bone marrow changes.

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

## Transparent MRI Scan Pricing (As of 1 March 2026)
For those considering an MRI scan, the typical pricing for musculoskeletal (MSK) MRI scans ranges from SGD $950 to $1,000. Actual pricing may depend on the specific body region being scanned, and fees should be confirmed during a consultation.

## Specialist Radiologist Report Included
Every MRI scan includes a formal report prepared by a specialist radiologist. This report provides detailed interpretation of findings and clinical correlation where applicable, all at no additional cost.

## MRI Images Provided
Patients will receive MRI images, either as films or digital copies, at no additional cost. These images can support second opinions, specialist consultations, insurance claims, or be kept for personal records.

## Insurance Documentation Support
The clinic provides documentation to support eligible claims under various insurance types, such as personal accident insurance, travel insurance, and company insurance plans. Please note that reimbursement depends on individual policy terms and insurer review, and claim approval cannot be guaranteed.

## Medisave Support
For eligible patients without insurance, Medisave may potentially allow up to $600 to be claimable, subject to CPF Board regulations and clinical eligibility. The terms vary, so confirmation is necessary for individual cases.

## Why Continuing Without Imaging May Delay Clarity
Without imaging, patients may experience ongoing trial-and-error therapy, leading to repeated treatment costs and persistent uncertainty. This approach often treats symptoms rather than addressing the root cause, resulting in delayed appropriate intervention.

The Role of MRI Scans in Diagnosis

# Persistent Numbness in Arm After Treatment — Should an MRI Scan Be Done?

## Why This Problem May Not Be Improving
Persistent numbness in the arm after treatment may not be improving due to several clinically relevant reasons, including:
