Rehabilitation after lumbar discectomy and decompression: walking, work and warning signs

The NHS lumbar decompression surgery pages describe operations that relieve pressure on the nerves in the lower spine, including removal of part of a disc. They give timings for the hospital stay, return to work and full activity, but do not give a day-by-day exercise programme or an exact date for driving. This guide reports those timings and says plainly where the detail has to come from your surgeon.

The NHS slipped disc page adds that surgery is not usually needed and is considered if symptoms have not improved with other treatments or if there is worsening muscle weakness or numbness. That context helps explain why the post-operative advice emphasises watching for new nerve symptoms.

The medical team will help you get up and move around as soon as possible after surgery, according to the NHS. The operation itself is described as taking around 2 to 4 hours, though it may take longer, and the hospital stay is around 2 to 5 days.

A catheter, if you had one, is usually removed after 1 or 2 days. Early walking is not just for comfort. It helps circulation, and it is how the team checks that your legs are working as expected before you go home.

The NHS says you may be able to return to work around 4 to 6 weeks after the operation, depending on the type of work you do and your doctor's advice. It also says it may take up to 12 weeks for you to be able to do all your usual activities.

For a desk worker, a return at the shorter end may be realistic with regular breaks to stand and walk. For someone whose job involves lifting, bending or long driving, the longer end is more likely, and a phased return or adjusted duties is worth asking about. The NHS notes that you may have to avoid activities such as driving or contact sports while you recover but gives no fixed date for driving, so ask the team and your insurer.

The NHS says you may need painkillers for several weeks after the operation. Pain from the wound and the back itself often differs from the leg pain you had before surgery, and leg symptoms can take time to settle even when the cause has been dealt with.

For general advice about the back, the NHS slipped disc page recommends starting gentle exercise such as walking, swimming and yoga as soon as you can, and staying active with exercise that does not cause pain or make back pain worse. After surgery, though, the specific permission to swim or do yoga should come from your surgeon, as wound healing and the type of operation matter.

The NHS lists several serious but uncommon risks of lumbar decompression surgery. Knowing them helps you tell routine soreness from something to report.

• Leak of spinal fluid, which may mean more surgery is needed.

• Damage to spinal nerves or paralysis.

• Back pain that does not get better.

• Other bones in the spine moving out of place after surgery.

The NHS says to contact the hospital or NHS 111 if you have new symptoms such as pain, weakness or numbness in your legs, or problems controlling when you pee or poo, or if the skin around your stitches is hot, itchy, oozing fluid or red.

The NHS slipped disc page lists emergency features of cauda equina syndrome: numbness around your bottom or genitals, being unable to pee, losing feeling in one or both legs, being unable to control when you pee or poo, or pain after a serious accident. It says not to drive yourself to A&E; ask someone to drive you or call 999 and ask for an ambulance.

Because the NHS pages leave some practical points open, a short list of questions at discharge can save worry later.

• Which movements, if any, should I avoid, and for how long?

• When can I start walking further, and is there a recommended daily target?

• Will I see a physiotherapist, and when?

• When can I drive, and what does my insurer need to know?

• Who do I contact, and how, if new symptoms appear?
