Understanding Knee Pain Symptoms

# Knee Pain That Feels Like Something Is Moving Inside — Do I Need an MRI Scan?

## Why This Problem May Not Be Improving
Persistent knee pain can stem from several clinical factors that might not have been fully addressed. It could be due to structural injury not previously detected, a disc or cartilage pathology, ligament or tendon injury, nerve compression, bone stress reactions, an incomplete or imprecise diagnosis, or a plateau after conservative treatment. Notably, if symptoms persist beyond 6–12 weeks, it may warrant further evaluation to gain clarity on the underlying issue.

## When Should an MRI Scan Be Considered?
An MRI scan may be considered if:
• 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 provides detailed evaluation of the knee’s soft tissues, including discs, ligaments, tendons, cartilage, meniscus, labrum, nerve roots, and bone marrow changes. It is important to note that an MRI is not always necessary in every situation.

## MRI Scan Safety
MRI scans are beneficial and considered safe for most patients. Unlike X-rays or CT scans, an MRI scan does not use ionising radiation; rather, it employs magnetic fields and radiofrequency signals. This technology is widely utilized for a detailed assessment of soft tissues in the body, including the knee.

## Transparent MRI Scan Pricing (As of 1 March 2026)
Most musculoskeletal (MSK) MRI scans are typically priced between SGD $950 to $1,000, depending on the specific body region being scanned. It is advisable to confirm fees during your consultation.

## Specialist Radiologist Report Included
Each MRI scan includes a formal report prepared by a specialist radiologist, offering a detailed interpretation of the findings and, where applicable, clinical correlation. This report is provided at no additional cost.

## MRI Images Provided

What To Expect When I Visit The Pain Relief Clinic

A typical visit will involve our doctor first understanding your medical history, concerns and previous experience with other pain treatments.

For patients who have consulted many people but have yet to receive a clear diagnosis, selecting an affordable imaging scan might be recommended to confirm the cause of your pain..

Some patients have already done scans with other doctors for their pain condition but are still not clearly told what they suffer from.

Dr Terence Tan is happy to offer you a second opinion and recommend how best to manage your condition.

We also see patients who already have a confirmed diagnosis from specialist pain doctors, but are "stuck” because treatment options offered are not practical or acceptable.

We can help by discussing options that you might have potentially never been told of.

A common experience is when a patient has already consulted a specialist doctor for pain management and is told to consider orthopaedic surgery which they find too aggressive.

Or they may have seen doctors for their pain and were prescribed painkillers with potential side effects which made them feel uncomfortable.

Many of our patients have also first tried complementary treatments or acupuncture with traditional Chinese pain doctors.

They look for a second opinion after finding any relief experienced from other treatments to be temporary or requiring repetitive treatments, which add up to time and cost.

Especially in such situations, we emphasize using non-invasive medical technology you likely have not been told about .

This can make a big difference to your results.
