This is a general guide, not your personal plan
Every patient and every procedure is different. These timelines reflect typical ranges — not what will happen to you specifically. Your personalized recovery plan, tailored to your anatomy, procedure, and health, will be reviewed with you before surgery and at each post-operative appointment.
The most common question Dr. Grewal hears before surgery: How long before I can go back to work? Play golf? Pick up my grandchild? The honest answer is that it depends — on the procedure, your health going in, how many levels were treated, and how consistently you follow the rehabilitation program. What the research does show: patients who follow a structured post-operative PT program through Go Rehab Physical Therapy recover significantly faster than those who don’t.
Lumbar Microdiscectomy
Indicated when a herniated lumbar disc is causing significant leg pain or neurological deficits unresponsive to 6–12 weeks of conservative care.
Day of surgery: Home that afternoon
Most lumbar microdiscectomies at Grewal Spine are same-day outpatient. Patients are walking within a few hours. What surprises most people is how quickly the shooting leg pain improves — often within the first day or two as the nerve root decompresses.
Week 1–2: Rest, but not bed rest
No bending, lifting over 5–10 lbs, or twisting (BLT precautions). Short walks — 10 to 15 minutes, 3 or 4 times daily — are encouraged and speed recovery. No driving while taking narcotic medication.
Weeks 2–6: Gradual return to activity
Walking increases. Light household activities resume. Most desk workers return at 2–4 weeks. Physical therapy starts around weeks 4–6 with core stabilization and posture work. Driving resumes 2–3 weeks post-op when off narcotics.
Months 2–3: Active rehabilitation
Progressive PT through Go Rehab — adding resistance and functional movement. Light aerobic exercise cleared at about 8–10 weeks. Manual workers often start modified duty around this time.
Months 3–6: Return to full work and most sports
Most patients — including physically demanding jobs — have returned to work. Running and sport-specific activities typically resume at 12–16 weeks. Greater than 90% of properly selected patients report significant improvement in leg pain.
Spinal Fusion (Open or MIS)
Indicated for spondylolisthesis, instability, recurrent disc disease, or stenosis with structural instability.
Days 1–3 (open) / Day 0–1 (MIS): Hospital or home
Open fusion requires a 2–4 day inpatient stay. MIS fusion is often discharged after 1 night or as an outpatient. A physical therapist visits bedside on post-operative day 1 to get you walking.
Weeks 1–6: Recovery at home with brace
A lumbar brace is typically prescribed for 4–8 weeks. Strict BLT precautions. Daily walks build gradually. The 2-week follow-up includes wound check and X-rays.
Months 1–3: Physical therapy begins
PT starts around 6–8 weeks with gentle core activation and walking progression. Most desk workers return to sedentary work at 4–8 weeks.
Months 3–6: Bone fusion consolidates
The bone graft integrates with the vertebral endplates — this biological process cannot be rushed. Activity restrictions lift progressively as imaging confirms fusion progress.
Months 6–12: Full return to all activities
Return to physically demanding work and recreational sports. Final imaging confirms solid fusion. Long-term outcomes for properly selected fusion patients are durable.
Cervical Disc Surgery — ACDF or Disc Replacement
Indicated for herniated cervical disc causing arm pain (radiculopathy) or cord compression (myelopathy) unresponsive to conservative care.
Day of surgery: Usually home the same day
Most single and two-level ACDF and disc replacements are outpatient procedures. A soft cervical collar may be worn for 2–4 weeks. Many patients are surprised by how quickly arm pain begins to improve — often within 24–48 hours.
Week 1–3: Swallowing and soreness — temporary
The anterior cervical approach passes near the esophagus, so mild swallowing difficulty in the first week is normal. Soft diet for a few days helps. Arm numbness and tingling may persist for weeks to months as nerve healing continues — this is expected.
Weeks 2–6: Return to desk work
Most desk workers return at 2–4 weeks. Driving resumes when off narcotics and the collar is discontinued. Neck-strengthening PT typically starts at 4–6 weeks.
Months 2–4: Fusion and strengthening
Progressive cervical and upper extremity strengthening. ACDF fusion confirmed on X-ray at 3–6 months.
Months 4–6: Full activity
Return to all activities including sports and physical work. ACDF has been performed for over 60 years with an excellent long-term evidence base.
