What is lumbar spinal stenosis?
At the centre of the spine, the spinal canal holds the spinal cord and the nerve roots. According to the American Academy of Orthopaedic Surgeons (AAOS), wear of the spine over the years can reduce this space: we speak of lumbar spinal stenosis when the nerves become squeezed in the lower back. The AAOS names arthritis as the most common cause: the discs settle, the small joints of the spine wear, small bony outgrowths (bone spurs) form and ligaments thicken. It occurs most often after 60; less often, the canal is narrow from birth.
The Swiss League against Rheumatism lists narrowing of the spinal canal among the identifiable causes of back pain, alongside the herniated disc.
For care options, see our Back pain page. This article focuses on symptoms and everyday life.
Lumbar spinal stenosis: what are the symptoms?
The AAOS describes:
- an ache or burning pain that starts in the buttock and travels down the leg, sometimes to the foot;
- numbness or tingling in the buttocks or legs;
- weakness in the legs, or a foot that "drops" and slaps the ground when walking.
Back pain itself may or may not be present. The most telling sign is the link with posture: standing or walking makes the pain worse, while sitting or leaning forward eases it. According to the AAOS, leaning forward increases the space available for the nerves. Doctors call this neurogenic claudication, meaning legs that become painful, heavy or weak when walking because the nerves are squeezed: the distance you can walk gets shorter.
Spinal stenosis, sciatica or something else?
Sciatica describes pain along the path of the sciatic nerve; lumbar spinal stenosis is one possible cause, as is a herniated disc. Leg pain when walking can also come from the arteries, when they do not supply the muscles well. If your legs hurt when you walk, see your doctor: a medical examination tells the causes apart and checks your circulation.
To make the diagnosis, the doctor relies on your symptoms and an examination of your back, and may then request an X-ray, MRI or CT scan. An MRI often shows signs of wear that are not necessarily linked to the pain, the League points out: read Lumbar MRI: disc problems explained.
Lumbar spinal stenosis: what to do day to day?
According to the AAOS, many people report that non-surgical treatments relieve their symptoms, even though they do not change the narrowing itself. The Swiss medical journal Revue Médicale Suisse describes the same picture: sitting down brings clear relief, and leaning on a shopping trolley lengthens the walking distance. It notes that the diagnosis is mainly clinical and that care includes active physiotherapy focused on posture and muscle strengthening.
Move with posture in mind. Stretching, massage and strengthening of the back and abdominal muscles often help manage symptoms, according to the AAOS. A stationary bike, ridden slightly bent forward, may be easier than walking.
Break up your walks. Rather than giving up outings, walk in stages and plan sitting breaks. Leaning on a trolley or using walking poles, with your upper body slightly forward, can extend the distance.
Stay active. The UK NICE guideline on low back pain and sciatica (NG59) puts exercise at the centre of care and recommends manual therapy only as part of a package that includes exercise. Medication is discussed with your doctor.
Lumbar spinal stenosis: treatment with or without surgery?
According to the AAOS, surgery is generally reserved for people whose quality of life is severely limited by pain and weakness, including difficulty walking for long. NICE suggests considering spinal decompression when non-surgical treatment has not improved pain or function and imaging is consistent with the symptoms.
Warning signs: when to seek help without delay
Go to the emergency department immediately if you have:
- numbness in your buttocks or genital area;
- loss of bladder or bowel control;
- loss of strength in your legs, or you cannot walk.
See your doctor soon if:
- weakness in your leg is getting worse or your foot catches when you walk;
- you have a fever, are losing weight for no reason or have a history of cancer;
- the pain becomes severe at night, at rest.
In the vast majority of cases, none of these signs is present.
Looking beyond the scan
The first consultation lasts 1.5 to 2 hours (CHF 182). Bring your medical file, your test results (X-rays, MRI, reports) and the list of your medications. We review your situation and build your plan together. Follow-up is then adapted to your progress. We work alongside your GP and the other professionals who care for you, in particular your physiotherapist.
Which approaches can play a part at Centre Algos?
Depending on your situation, several approaches can be combined, alongside medical care and physical activity:
- Naturopathy: diet, weight, sleep and daily rhythm, to work on habits that can influence pain.
- Cupping: applied to the lower back and buttocks, it can help release muscle tension.
- Percutaneous hydrotomy: micro-injections under the skin. After assessment, when no warning signs are present and in agreement with your medical care, it can be discussed as a complementary option; it can bring relief, with no guaranteed result. We explain how it works, its limits and its contraindications; results vary from person to person. If hydrotomy is part of your plan, price on quotation, set at the first consultation according to your situation.
Everyone responds differently: the aim is to live your days better and keep your independence, without promising a result. For non-surgical options for back pain in general, read Back pain without surgery.
