After a lumbar laminectomy or other spinal decompression surgery, most people go home the same day or within a few days, return to work at around four to six weeks, and are back to their usual activities by about THREE months.
Leg pain, heaviness and walking distance usually improve the most.
Back pain is less predictable. If you go in expecting better legs and a back that may still ache some days, you’ll judge your recovery fairly.
Recovery is slower if a fusion was added to the decompression. The timeline below is for decompression alone.
What the operation does
- Decompression is the umbrella term. It means making more room for squeezed nerves in the lower back
- Laminectomy removes the lamina, the bony roof at the back of a vertebra, to open up the spinal canal
- Discectomy removes part of a disc pressing on a nerve. It is often done on its own for a slipped disc. See microdiscectomy recovery
- A fusion is sometimes added if the spine is unstable, for example when a vertebra has slipped forward
Week by week
- Days 0 to 3: up and walking the same day or the next. Many people go home the same day. Others stay two to five days, depending on the operation and their general health
- Weeks 1 to 2: short walks several times a day, a little further each day. Change position often. Painkillers are commonly needed for several weeks. Take them as prescribed so you can keep moving
- Weeks 2 to 6: walks get longer, and gentle exercises start, often with a physio. Leg symptoms settle further. Numbness usually lags behind pain
- Weeks 4 to 6: back to work for many people, especially desk jobs. A phased return helps
- Weeks 6 to 12: strengthening for your trunk, hips and legs. Heavier jobs and lifting come back gradually
- Months 3 and beyond: most usual activities are back. Nerve symptoms can keep improving for months
Your surgeon may give you different limits. Use theirs.
Walking after decompression
- Walking is the main exercise. It eases stiffness and lowers the risk of blood clots
- Build distance in small steps. Several short walks beat one long one early on
- Walking and standing usually get easier. For people with spinal stenosis, that is often the main reason for the operation
- Your legs may be out of condition. Months of limited walking before surgery can leave muscles weak. Stamina takes weeks to rebuild, even once the nerves are free
Surgery gives the nerves room. Walking gives you your legs back.
Sitting, driving, work and lifting
- Sitting: short spells at first. A firm chair with good back support is easier than a soft sofa
- Driving: once you can do an emergency stop confidently and you’re off painkillers that make you drowsy. Start with short trips. Check with your insurer
- Going back to work: around four to six weeks for many people. Jobs with lots of lifting, walking or long sitting can take longer
- Lifting: light things held close to your body early on. Heavy lifting, especially with bending and twisting, builds up over the first few months
- Exercise: walking from day one. Swimming and an exercise bike usually come a few weeks later, once the wound has healed
What’s normal, and what to expect long term
- Soreness around the wound for the first few weeks
- Leg twinges as the nerves settle. A steady trend matters more than one bad day
- Numbness that lingers. A nerve squeezed for a long time recovers slowly, and some numbness can stay for good
- Some back ache. Decompression is aimed at the legs. Back pain often improves less
- A smaller group need more surgery later, for example if the spine becomes unstable or narrowing develops again. Staying active and keeping your trunk and hips strong is sensible long-term care
If you’re still deciding whether to have surgery, see spinal stenosis.
If a fusion was added, see lumbar spinal fusion recovery.
The NHS has a helpful guide to recovering from lumbar decompression surgery.
Go to the emergency department now if
- New numbness around your genitals or buttocks, the area that would touch a saddle
- New trouble peeing, not being able to pee, or leaking pee or poo without knowing
- New or rapidly worsening weakness in one or both legs
- Chest pain or sudden shortness of breath. Call emergency services
Call your surgeon today if
- The wound is red, hot, swollen or oozing
- You have a fever or feel unwell
- Clear fluid is leaking from the wound, or you get a severe headache that’s worse sitting or standing and better lying flat
- Your calf is painful, swollen or warm
- Leg pain comes back strongly after it had settled
Mention it at your next review if
- Your walking distance isn’t improving after several weeks
- Your foot still catches or slaps when you walk
- Back pain is stopping you getting back to work
Surgery frees the nerves, but three months of steady walking is what rebuilds your legs.
