Dr Diana Chan is a Pain Medicine Specialist with over 20 years of experience and more than 2,000 pain procedures performed. She is the former Head of the Department of Pain Medicine at Singapore General Hospital and founder of the SingHealth Duke-NUS Pain Centre. She treats lower back pain using a combination of accurate diagnosis, minimally invasive interventional procedures, and long-term pain management planning with the goal of getting patients back to normal function, not just masking the pain.
Lower back pain isn’t a single condition, it’s a symptom that can come from several different structures in the spine, muscles, or nerves. Getting the right treatment starts with identifying which one is actually responsible.
From poor posture, heavy lifting, or sudden movement. Usually improves within a few weeks but can become chronic if the underlying movement pattern isn’t corrected.
The discs between vertebrae lose height and cushioning with age, which can lead to persistent stiffness and pain.
When the soft inner core of a spinal disc pushes through its outer layer and presses on a nearby nerve. This often causes pain that radiates into the buttock or leg.
Nerve pain caused by irritation or compression of the sciatic nerve, typically felt as a sharp or burning pain running from the lower back down one leg.
Wear and tear in the small joints connecting each vertebra, often worse with bending or twisting.
Narrowing of the spinal canal that puts pressure on nerves, more common with age and often worse when standing or walking.
Pain originating in the muscles and surrounding connective tissue, often linked to prolonged sitting or repetitive strain.
Most lower back pain is not dangerous, but certain symptoms warrant urgent medical attention rather than self-management. See a doctor promptly if your back pain comes with:
These “red flag” symptoms can point to nerve compression, infection, fracture, or in rare cases something requiring more urgent intervention, which is one reason a proper clinical assessment matters more than guessing based on symptoms alone.
An accurate diagnosis is the foundation of effective treatment, treating the wrong structure, or treating a symptom without understanding its source, is a common reason patients feel “stuck” after months of generic treatment.
A typical first consultation includes:
How the pain started, what makes it better or worse, whether it radiates into the leg, and how it’s affecting daily activities, sleep, and work.
Assessing range of motion, muscle strength, reflexes, and specific movements or positions that reproduce the pain, which helps localise the source.
X-rays to assess bone alignment and joint changes, or MRI when there’s suspicion of disc herniation, nerve compression, or other soft tissue involvement. Imaging is used to confirm a clinical suspicion, not as a blanket first step for every patient.
In some cases, a precisely placed local anaesthetic injection is used to confirm which structure is actually generating the pain, rather than relying on imaging findings alone. This is a hallmark of interventional pain medicine and helps avoid treating the wrong target.

As an interventional pain specialist, Dr Chan’s approach centres on minimally invasive treatment, used alongside medication and rehabilitation, with surgery considered only when appropriate and typically as a later step.
Anti-inflammatory medication delivered directly to the affected nerve root, often used for disc-related nerve pain or sciatica.
Targeted injections that interrupt pain signals from a specific nerve or joint, used both diagnostically and therapeutically.
A minimally invasive procedure that uses heat to disrupt pain signals from facet joints, offering longer-lasting relief for suitable patients.
For patients with chronic or complex pain that hasn’t responded to other treatments, devices that modulate nerve signalling can offer significant relief.
Dr Chan holds a Graduate Diploma in Acupuncture (MOH-recognised) and integrates it where clinically appropriate as part of a broader pain management plan.
Coordination with physiotherapy and other allied health support to address movement, strength, and posture alongside pain relief.

Many people in Singapore start with a GP, physiotherapist, TCM practitioner, or chiropractor for back pain and for mild, short-term strain, these are often reasonable first steps. A pain specialist becomes particularly valuable when:
A pain specialist like Dr Chan has training specifically in diagnosing the exact source of pain and in interventional procedures that aren’t available through physiotherapy, TCM, or chiropractic care, including nerve blocks, radiofrequency ablation, and neuromodulation.
Dr Chan’s approach is shaped as much by personal experience as clinical training, including her own long-term shoulder injury and caring for her father through cancer-related pain. That experience underpins a philosophy centred on three things: an accurate diagnosis before any treatment is proposed, using the least invasive effective option first, and treating pain in the context of a patient’s overall quality of life, not just a symptom to be suppressed.

Pain triggered specifically by bending forward often points to a disc-related issue, such as a bulging or herniated disc, since bending increases pressure on the front of the spinal discs. If it’s accompanied by pain running down the leg, it’s worth having it assessed rather than waiting for it to resolve on its own.
Morning back pain can result from an unsupportive mattress or sleep position, but it can also indicate inflammatory causes or facet joint stiffness that eases with movement over the day. If it lasts more than an hour after waking, it’s worth mentioning to a doctor rather than assuming it’s the mattress.
Acute lower back pain typically resolves within a few days to weeks, often linked to a specific strain or movement. Chronic lower back pain is defined as pain lasting more than 12 weeks, and it usually needs a different treatment approach, one focused on identifying the specific underlying source rather than general rest and pain relief.
This depends entirely on the cause and the treatment used. A nerve block may provide relief within days, while rehabilitation-based approaches for chronic pain may take several weeks of a combined plan to show lasting improvement. A personalised timeline is usually clearer after the initial assessment.
