Low Back Pain Treatment on the GST Road — Advanced Non-Surgical Spine Care at Singaperumal Koil

The lumbar intervertebral disc is a sophisticated shock-absorbing structure positioned between each pair of lumbar vertebrae. It consists of two components:

The nucleus pulposus — the soft, gel-like inner core that absorbs compressive load and distributes forces evenly across the vertebral endplate.

The annulus fibrosus — the tough, multi-layered outer ring that contains the nucleus, resists rotational and shear forces, and maintains disc height.

The disc has an extremely poor blood supply — one of the poorest of any structure in the body. This is why disc injuries heal so slowly and why degeneration, once established, tends to progress rather than resolve without intervention.

When the annulus tears — from acute injury, sustained overload, or cumulative degeneration — the nucleus can bulge or extrude outward (disc herniation). Even without herniation, internal disc disruption — tears within the annulus — generates significant discogenic pain through the pain-sensitive nerve fibres within the outer annulus.

At the back of each lumbar vertebral level, two small synovial joints — the facet joints (also called zygapophyseal joints) — connect adjacent vertebrae and control the direction and range of spinal movement. Like all synovial joints, the facets are lined with cartilage, enclosed in a joint capsule, and lubricated by synovial fluid.

With age, sustained loading, and degenerative disc narrowing — which transfers increased load to the facets — these joints develop osteoarthritic changes. The cartilage thins. Osteophytes form. The joint capsule becomes inflamed. The result is facet-mediated low back pain — characteristically worse with spinal extension (bending backwards) and rotation, and often with referred pain into the buttock and thigh.

Facet joint pain accounts for approximately 15–45% of chronic low back pain in patients over 50 — making it one of the most important pain sources to identify and treat.

Eight pairs of nerve roots exit the lumbar spinal canal through the intervertebral foramina — narrow bony channels between adjacent vertebrae. When a herniated disc, osteophytic spur, or thickened ligament compresses one of these nerve roots, it generates the characteristic pain of lumbar radiculopathy — pain, numbness, tingling, or weakness in the specific limb territory supplied by that nerve root.

L4 root compression — lateral thigh, inner leg, anterior shin. L5 root compression — outer shin, top of the foot, great toe. S1 root compression — back of the thigh and leg, outer foot, small toes.

Nerve root pain — sciatica — has its own dedicated treatment pathway: the epidural steroid injection. This is covered in full in Section 7.

The most common cause of chronic low back pain under 60 — and the most underdiagnosed because early disc degeneration on MRI is often dismissed as "normal ageing." Internal disc disruption — tears within the annulus without necessarily producing obvious disc herniation — generates pain through the sensitised nociceptors within the outer annular fibres. This pain is characteristically:

Centralised to the low back — without leg pain in early stages

Worsened by sitting — particularly on hard surfaces

Worsened by flexion movements — bending, lifting, reaching forward

Relieved by lying flat — which reduces intradiscal pressure

Worse in the morning after sleep — as the disc rehydrates overnight and pressure increases

When the nucleus pulposus breaches a weakened annulus and extends outward, it can directly contact and compress the adjacent nerve root. This is the classical slipped disc — presenting with back pain combined with radiating leg pain, numbness, tingling, or weakness in the specific nerve root distribution.

Disc herniations are classified by their extent: bulging (annulus intact but deformed), protrusion (nucleus extends beyond the disc but contained by outer annular fibres), extrusion (nucleus breaches all annular layers), and sequestration (fragment of nucleus separated from the disc and free in the spinal canal).

A significant proportion of contained disc herniations — protrusions — resorb naturally over 6–12 months. Extruded and sequestrated fragments may also resorb. However, the pain during this period is significant, and targeted epidural intervention dramatically reduces pain severity and recovery time during the natural resolution process.

Age-related degenerative changes involving multiple components of the lumbar spine simultaneously: disc height loss, osteophyte formation, facet joint arthritis, and ligamentum flavum thickening. Lumbar spondylosis typically produces a complex, multi-level pain picture — a combination of discogenic, facet, and sometimes neural elements at different levels.

Workers at the Oragadam Industrial Corridor — Renault-Nissan, Daimler, Apollo Tyres, and the surrounding manufacturing plants — and those employed in heavy construction and logistics along the GST Road perform daily work that places significant, repetitive loads on the lumbar spine. Heavy lifting with spinal flexion-rotation, sustained awkward postures, and whole-body vibration from vehicle operation are the dominant occupational risk factors for accelerated disc degeneration and lumbar spondylosis in this population.

Residents of Kattankulathur, Maraimalai Nagar, and Guduvancheri involved in physically demanding work present to Dr. RRB Pain Care with lumbar disc and facet pathology at earlier ages than would typically be seen in sedentary populations.

IT professionals and desk workers at Mahindra World City, Kattankulathur, and WFH residents across the GST Road corridor represent the other end of the spectrum. Sustained lumbar flexion in a seated position — particularly on poorly configured workstations — increases intradiscal pressure substantially compared to standing. Prolonged sitting without postural breaks is a well-documented accelerator of disc degeneration and the development of discogenic back pain in younger working adults.

Different pain sources produce characteristic, distinguishable symptom patterns. Identifying which pattern applies helps confirm the diagnosis before any procedure is planned.

Deep, central low back pain — often described as aching, boring, or pressure-like

Worsened by sitting — particularly slumped sitting with lumbar flexion

Worsened by flexion-dominant activities — bending forward, picking up objects, tying shoes

Relieved by standing and walking — which reduces intradiscal pressure

Worse in the morning — disc rehydrates overnight, increasing pressure

May radiate into the buttock — but not typically below the knee without nerve root involvement

Increased with coughing, sneezing, or straining — Valsalva manoeuvre increases intradiscal pressure

Localised pain on one or both sides of the lower lumbar spine

Worsened by spinal extension — standing tall, bending backwards, walking downhill

Worsened by rotation — twisting to one side

Relieved by sitting and flexion — which opens the facet joints

Referred pain into the buttock and posterior thigh — rarely below the knee

Stiffness that is worst first thing in the morning and after prolonged inactivity

Back pain accompanied by shooting, burning, or electric pain radiating from the back or buttock into the leg — often below the knee

Numbness or tingling in a specific part of the leg or foot

Weakness — difficulty lifting the foot, weakness when rising from squatting

Worsened by sitting and better with walking — in classical L4-L5 and L5-S1 disc compression

Positive straight leg raise test — lifting the affected leg with the knee straight reproduces the leg pain

Assessment of lumbar range of motion in all planes

Neurological examination — reflexes, dermatomal sensory testing, myotomal strength testing

Provocation tests — straight leg raise, femoral nerve stretch, Kemp's test (facet provocation), compression and distraction tests

Palpation of vertebral levels and paraspinal soft tissues — identifying facet tenderness and muscle pathology

The primary imaging investigation for low back pain with structural pathology. MRI provides:

Disc morphology — height, hydration status, annular integrity, herniation type and level

Nerve root assessment — compression, swelling, contact with herniated disc material

Facet joint assessment — cartilage loss, joint space narrowing, osteophyte formation, synovitis

Spinal canal and foraminal dimensions — identifying stenosis

Modic changes — bone marrow signal changes at vertebral endplates associated with discogenic pain

Lumbar X-ray in standing position assesses disc space height, vertebral alignment, osteophyte formation, and gross structural changes. Essential for identifying instability, listhesis (vertebral slippage), and scoliosis that may influence treatment planning.

Stimulate nucleus pulposus cell activity — supporting the disc's resident cell population that maintains the extracellular matrix

Promote proteoglycan synthesis — the molecule responsible for the disc's water-attracting, shock-absorbing properties

Reduce inflammatory mediators — TNF-α and IL-1β, which are elevated in degenerated discs and sensitise disc nociceptors

Support annular repair — growth factors stimulate fibroblastic activity in the annulus fibrosus that has sustained micro-tears

The clinical result is reduction of discogenic pain — through both biological disc improvement and reduction of the inflammatory pain-generating environment within the disc.

Evidence: The first double-blind RCT of intradiscal PRP for discogenic low back pain reported statistically significant improvements in pain scores and functional rating at 8-week follow-up, with no adverse events including no disc infection, neurologic injury, or progressive herniation. Long-term efficacy was confirmed in an RCT with 5–9 years of follow-up. Critically, a positive correlation between platelet concentration of PRP and clinical outcomes was identified — which is why Dr. RRB Pain Care prepares PRP to a consistent, high-platelet concentration.

Reduces the inflammatory response around the compressed nerve root

Decreases nerve oedema (swelling of the nerve)

Blocks the inflammatory cascade triggered by the herniated disc material

Provides a therapeutic window during which the disc's natural resorption can proceed and physiotherapy can progress

Lumbar Interlaminar Epidural (LESI): Delivers medication to the posterior epidural space. Appropriate for bilateral symptoms, central disc herniation, or when a broad epidural distribution is needed.

Transforaminal Epidural (TFESI) — Selective Nerve Root Block: Delivers medication specifically to the foramen of the affected nerve root — placing the steroid directly adjacent to the nerve at its point of compression. This is the more targeted approach — and is particularly effective for unilateral radiculopathy from a posterolateral disc herniation.

Both procedures are performed under fluoroscopic guidance with contrast confirmation at Dr. RRB Pain Care — ensuring the medication reaches the intended epidural space with confirmed spread.

Performed as a day procedure under local anaesthesia

Procedure time: 20–30 minutes

Most patients notice meaningful reduction in leg pain within 3–7 days

Relief typically lasts 4–12 weeks — providing a window for nerve recovery and physiotherapy

May be repeated at appropriate intervals if clinically indicated

For acute disc herniations in young patients — the nerve root injection combined with physiotherapy allows many patients to avoid surgery entirely as the disc resorbs naturally

Facet Joint Injection and Radiofrequency Ablation — For Facet-Sourced Back Pain:

When clinical examination and diagnostic injection confirm the facet joints as the primary source of low back pain — rather than the disc or nerve root — the treatment pathway is entirely different.

The facet joints receive their pain innervation from the medial branch nerves — small nerve branches arising from the dorsal rami at each lumbar level. A medial branch block delivers local anaesthetic to these specific nerves under fluoroscopic guidance.

Diagnostic: If the block produces significant pain relief (typically 50–80% or greater reduction), it confirms the facet joints at that level are the primary pain source. This positive response then justifies proceeding to radiofrequency ablation.

Therapeutic: The block itself provides pain relief lasting hours to days — sometimes longer — offering immediate symptomatic benefit while longer-term management is planned.

For patients whose medial branch block has confirmed facet joint-sourced back pain, Radiofrequency Ablation (RFA) of the medial branch nerves provides the most sustained non-surgical relief available for this condition.

RFA uses precisely controlled thermal energy to selectively ablate the medial branch nerves supplying the painful facet joints — interrupting the pain signal from the joint to the brain without affecting motor function or the joint's mechanical contribution to spinal stability.

Significant pain reduction beginning 1–3 weeks after the procedure

Relief lasting 12–18 months or longer in most patients

The procedure can be safely repeated when pain returns as the nerves slowly regenerate

Patients report improved walking tolerance, reduced morning stiffness, and ability to engage more effectively in rehabilitation

For patients with a complex pain picture involving sympathetic nervous system components — including certain post-surgical back pain presentations and CRPS involving the lower limb — a lumbar sympathetic block interrupts the sympathetic contribution to the pain signal.

The deep stabilising muscles of the lumbar spine — the transversus abdominis, multifidus, pelvic floor, and diaphragm — form the core stability system that protects the lumbar discs and facet joints from excessive load during movement. In patients with chronic low back pain, multifidus — the deepest spinal muscle — atrophies selectively at the painful level, reducing spinal stability and increasing load on the painful structure.

Targeted rehabilitation restores this muscle function — not with generic "core exercises," but with specific motor control re-education:

Transversus abdominis activation — diaphragmatic breathing with abdominal draw-in

Multifidus rehabilitation — specific prone extension exercises targeting the affected lumbar level

Bird-dog progression — quadruped opposite arm and leg extension, building lumbar stability under controlled load

Dead bug exercises — supine leg extension with arm opposition, challenging core without lumbar flexion stress

McKenzie extension exercises — for disc-sourced pain with centralisation response

Lumbar rotation stretches — for facet-sourced stiffness

Hip flexor lengthening — tight iliopsoas increases lumbar lordosis and facet compressive load

For IT professionals and desk workers at Kattankulathur and Mahindra World City:

Sitting with lumbar lordosis preserved — lumbar support roll or ergonomic chair with lumbar support

Screen at eye level — laptop stands and external monitors eliminate the forward head posture

Standing desk or sit-stand alternation — reducing cumulative intradiscal pressure from sustained sitting

Scheduled movement breaks — standing and walking for 2–3 minutes every 30–40 minutes of computer work

Hip hinge lifting technique — keeping the lumbar spine in neutral extension while bending through the hips and knees

Workstation height adjustment — ensuring the work surface does not require sustained lumbar flexion

Anti-fatigue mats — reducing vibration and impact transmission to the lumbar spine

Shift planning with micro-recovery periods — brief seated rest every 45–60 minutes of continuous standing or lifting

Every kilogram of excess body weight adds load to the lumbar disc and facet joint with every step. Weight reduction — even moderate — reduces spinal loading, slows disc degeneration, and improves the outcomes of every interventional treatment offered.

Surgery is not the answer for the vast majority of low back pain — but it is the right answer for some specific presentations. Dr. RRB will tell you clearly if your condition warrants surgical referral.

Cauda equina syndrome — compression of the bundle of nerve roots in the lower spinal canal causing bowel or bladder dysfunction, saddle anaesthesia, and rapid-onset bilateral leg weakness. This is a surgical emergency requiring immediate assessment.

Progressive neurological deficit — worsening leg weakness or footdrop from nerve compression that is not recovering with conservative management

Spinal instability — spondylolisthesis (vertebral slippage) causing significant mechanical instability requiring fusion

Severe spinal stenosis — severe multi-level narrowing causing neurogenic claudication unresponsive to all non-surgical management

Dr. RajaRajan Balasubramanian holds the FIPP (Fellow of Interventional Pain Practice, World Institute of Pain, USA) — the international certification that validates competency in advanced lumbar interventional procedures to the highest global standard — and the DABRM (American Board of Regenerative Medicine) — the certification that specifically validates intradiscal biological therapy expertise. He is one of fewer than five specialists in India to hold both simultaneously.

Low back pain has persisted for more than 6–8 weeks without meaningful improvement

Pain is radiating into one or both legs — numbness, tingling, or weakness alongside back pain requires neurological assessment

You have an MRI showing disc herniation, disc degeneration, or facet arthritis — and you want to understand your non-surgical treatment options

You have been offered lumbar spine surgery and want a specialist second opinion on whether non-surgical interventional management is appropriate first

Pain is disrupting your sleep, limiting your ability to work, or preventing you from performing your daily routine

You are a factory worker at Oragadam or a desk professional at Kattankulathur with recurrent or chronic low back pain that physiotherapy alone has not resolved

You have had repeated courses of oral medication and physiotherapy with only temporary improvement — targeted interventional treatment may address the structural pain source that conservative management cannot reach

Emergency: Any back pain accompanied by difficulty controlling bladder or bowel, or rapidly progressive leg weakness — seek immediate assessment. This may indicate cauda equina syndrome.

A significant proportion of disc herniations — particularly protrusions and some extrusions — resorb naturally over 6–12 months as the body's immune system gradually reabsorbs the herniated material. During this period, a lumbar epidural steroid injection dramatically reduces nerve root pain and allows normal activity and physiotherapy to proceed. Intradiscal PRP may be added to support the biological environment of the disc during this natural resolution process. For contained disc herniations without progressive neurological deficit, the combination of targeted epidural injection and physiotherapy allows the majority of patients to avoid surgery as the disc resorbs. Dr. RRB will advise on whether your specific herniation type and neurological status make non-surgical management appropriate.

Not the same injection for every patient. Not "rest and see." The actual source of your back pain — identified, confirmed, and treated with the procedure that matches your specific diagnosis.
