What Is a Herniated Disc?
A herniated disc occurs when the soft inner nucleus (nucleus pulposus) of an intervertebral disc pushes through a tear in the tougher outer ring (annulus fibrosus), compressing nearby nerve roots or the spinal cord. This compression triggers both mechanical pressure on the nerve and a chemical inflammatory response — the combination produces the characteristic symptoms of herniated disc disease. Disc herniations are most common at L4-L5 and L5-S1 in the lumbar spine, and C5-C6 and C6-C7 in the cervical spine.
A bulging disc is distinct: the disc expands symmetrically beyond its normal boundaries but the outer ring remains intact. While less severe structurally, a bulging disc can still compress nerve roots and cause significant pain. Both conditions are effectively treated with Dr. Qureshi's non-surgical interventional approach.
The good news: Most herniated discs improve significantly with non-surgical treatment. Studies show that disc material often reabsorbs over 6–12 months, and up to 90% of patients achieve satisfactory relief without surgery when managed appropriately.

How Disc Herniations Cause Pain
Pain from a herniated disc comes from two mechanisms working together. First, the physical mass of the herniated material presses on the nerve root mechanically. Second — and often more important — the nucleus pulposus contains inflammatory proteins (including phospholipase A2 and cytokines) that directly irritate the nerve, triggering an intense local inflammatory response even without significant compression. This is why epidural steroid injections, which deliver anti-inflammatory medication directly to the inflamed nerve root, are often so effective.
Common Symptoms
- Lumbar herniation: Sharp, shooting pain from the low back through the buttock and down the leg (classic sciatica); numbness or tingling in the leg, calf, or foot; muscle weakness; pain that worsens with sitting, coughing, or sneezing
- Cervical herniation: Neck pain radiating into the shoulder, arm, or hand; numbness or tingling in the fingers; weakness in shoulder, arm, or grip; pain that worsens with neck extension or rotation
Diagnosis
Diagnosis begins with a clinical history and neurological examination. Dr. Qureshi assesses the pattern of pain, sensory changes, reflexes, and motor strength to identify which nerve root level is involved. MRI provides detailed visualization of disc morphology and neural compression. In cases where clinical picture does not clearly match imaging findings, a selective nerve root block or discography can confirm which level is generating symptoms before definitive treatment. For vertebral compression fractures that may mimic disc symptoms, kyphoplasty is also available.
Non-Surgical Treatment Options
- Epidural steroid injections (ESIs) — the most evidence-based non-surgical treatment; delivers corticosteroid directly to the inflamed nerve root with fluoroscopic guidance, reducing inflammation and providing relief in most patients within 1–2 weeks. Learn about epidural steroid injection side effects and what to expect
- Selective nerve root blocks — more targeted placement immediately adjacent to the specific affected nerve root, useful for both diagnosis and treatment
- Physical therapy coordination — traction, core stabilization, and nerve mobilization once acute inflammation is controlled
- Spinal cord stimulation — for persistent neuropathic symptoms that fail to resolve with injections and therapy
Deciding between continued non-surgical care and surgery can be complex. Learn more about back pain surgery vs. injection therapy to understand the options.
When Is Surgery Necessary?
Surgery is typically reserved for progressive neurological deficits (worsening weakness or loss of bladder and bowel control), failure of 6+ months of aggressive non-surgical management, or intractable pain significantly impacting quality of life. The majority of Dr. Qureshi's patients achieve their goals without surgical consideration. When surgery is appropriate, Dr. Qureshi provides a direct referral to a trusted spine surgeon in the Greater Houston network.
Recovery Timeline
Acute disc herniations often improve significantly within 6–12 weeks with appropriate treatment. Epidural steroid injections can dramatically accelerate this timeline — many patients notice meaningful improvement within 1–2 weeks of their first injection. The disc herniation itself may take months to resorb, but pain typically resolves well before the structural changes fully reverse. Dr. Qureshi monitors progress and adjusts the treatment plan accordingly.
