Sciatica: leg pain, what to do about it, Luxembourg

Sciatica is pain that follows the path of the sciatic nerve, from the lower back down to the foot, passing through the buttock and the back of the thigh. It's most often caused by a slipped (herniated) disc pressing on a nerve root in the lower back, sometimes also by a narrowing of the canal the nerves pass through. A GP is usually the first point of contact, with referral to a neurologist or orthopaedic surgeon possible if the situation calls for it.

Recognising sciatica pain

Unlike ordinary back pain, sciatica pain typically radiates down the leg, usually on one side, following a specific path that can reach as far as the calf or foot. It sometimes comes with tingling, numbness or a burning sensation along that path. Coughing, sneezing or sitting for long periods often make it worse, while certain positions bring relief. This pain can be genuinely disabling in the first few days, which doesn't stop the vast majority of cases from resolving well.

What actually helps recovery

Contrary to a common assumption, strict bed rest isn't one of the recommended solutions: staying lying down for more than a day or two tends to slow recovery rather than help it. Moving gradually, walking as soon as the pain allows, and returning to normal activities as soon as possible all support faster healing. Suitable painkillers, prescribed by the doctor, help get through the most painful phase without holding back this return to activity. A physiotherapist can suggest targeted exercises once the acute phase has passed. In the vast majority of cases, symptoms improve clearly within a few weeks, with a gradual return to normal life; patience, hard as it is with pain, is part of the treatment.

When are tests actually needed

Typical sciatica, with no worrying signs, generally doesn't need immediate imaging: tests are reserved for situations that don't improve after several weeks of well-managed care, or that show particular warning signs. An MRI scan can then confirm the exact cause and guide any specialist care, without that necessarily meaning surgery.

Warning signs worth knowing

Some rarer signs call for urgent care rather than waiting: marked weakness in the leg or foot, for example a clear difficulty walking on heels or tiptoes, loss of sensation around the anus or genitals, or new problems controlling bladder or bowel function. This combination of symptoms, known as cauda equina syndrome, is a surgical emergency and means calling 112 or going straight to the emergency department, since a delay in treatment can leave permanent after-effects.

When is surgery considered

Surgery is needed for only a minority of sciatica cases, when well-managed medical treatment has failed after several weeks, pain has become unbearable despite suitable treatment, or a neurological deficit is worsening. It aims to remove the part of the disc pressing on the nerve and, when it's appropriate, gives good results for leg pain. Recovery from surgery still calls for a gradual return to activity under guidance rather than an assumption that the pain will simply be gone for good the moment the operation is over. Pregnancy is another common trigger, since the added weight and shifted posture can put extra pressure on the lower back; the same general advice applies, alongside guidance from a midwife or physiotherapist on safe positions and movements.

Reducing the risk of a recurrence

Once the pain has settled, a few habits help lower the chance of another episode without needing to overhaul daily life. Strengthening the core and back muscles gradually, once the acute phase is well behind, gives the spine better support. Avoiding long periods sitting without moving, adjusting how heavy objects are lifted — bending the knees rather than the back — and staying at a healthy weight all reduce the strain on the lower spine over time. None of these measures guarantees against a future episode, since disc wear also plays a role that can't always be controlled, but together they make a real difference for many people who've already had one bout of sciatica.

Care pathway in Luxembourg

The GP first assesses the sciatica and prescribes physiotherapy or suitable painkillers if needed. If it doesn't improve, they refer to a neurologist or orthopaedic surgeon for a specialist opinion. Consultations, imaging and physiotherapy are covered by the Caisse nationale de santé under the usual reimbursement rules; details are available at cns.lu.
