The spinal canal is the tunnel the spinal cord and nerve roots run in, formed by the vertebral bodies in front, the vertebral arches and facet joints behind and the ligaments in between. With the years the discs get lower and bulge backwards, the facet joints enlarge with osteoarthritis, and the yellow ligament (ligamentum flavum) thickens and folds: all of it takes room from the tunnel and from the side canals where the nerve roots exit. As long as there is margin, nothing is noticed. When the canal becomes narrow enough, the nerve roots and their blood supply are compressed in the upright position, because the arch in the lower back then makes the canal even narrower, and released when you bend forward or sit down, because the canal then widens by 10–20 per cent. That is why people with stenosis walk leaning forward, manage the bike and the shopping trolley but not a walk, and rest by sitting or bending, not by standing still. The symptoms are called neurogenic claudication: heaviness, numbness, weakness, cramp or ache in buttocks, thighs and lower legs, usually both sides, coming after a certain walking distance and forcing you to stop. Back pain is often present but not dominant. Stenosis in the neck (cervical stenosis) is less common and gives other symptoms: clumsy hands, difficulty doing up buttons, balance problems, a stiff gait; it should always be assessed. The diagnosis is made on the symptom picture plus MRI, but the MRI image doesn't decide treatment: many over 60 have a narrow canal on imaging without symptoms, and the degree of narrowing correlates poorly with the degree of symptoms. It is how you function that governs.
Stenosis, herniated disc/sciatica or claudication in the legs?
| Spinal stenosis | Herniated disc / sciatica | Vascular claudication (intermittent claudication) | |
|---|---|---|---|
| Age | Usually over 60 | Usually 30–50 | Over 50, smokers, diabetes |
| Triggered by | Walking and standing upright; also standing still | Sitting, bending forward, coughing, lifting | Walking (exertion), not standing still |
| Relieved by | Bending forward, sitting, cycling, shopping trolley, uphill | Lying, walking, standing; sitting is worst | Standing still, in any position |
| Where | Buttocks, thighs, lower legs, often both sides; heaviness and numbness more than sharp pain | One leg, a sharp strip down to the foot; often more pain in the leg than the back | The calf (sometimes thigh, buttock), cramp-like ache, both or one |
| Walking distance | Varies day to day, downhill is worse (more arch) | Not distance-dependent | The same distance every time, downhill easier |
| Other | Difficulty standing straight for long, walks leaning forward | Reduced reflex, weakness in one muscle group | Weak pulses in the feet, cold feet, thin skin, poor wound healing |

You can have two at once, and hip osteoarthritis gives groin and thigh pain when walking that can also be confused; see hip pain. The doctor tells them apart with examination, an ankle-brachial index and if needed MRI.
When to seek care
- Urgently, the same day: new numbness in the genital area, inner thighs or around the anus; difficulty urinating, emptying the bladder or holding urine; rapidly increasing weakness in one or both legs; severe back pain with fever or after a fall. It can be cauda equina syndrome, which is operated within hours.
- Your doctor: the walking distance has shrunk so that daily life is limited; numbness or weakness that increases; symptoms in both legs; clumsy hands or balance problems (the neck); symptoms not improved in six to eight weeks with self-care. Ask for a physiotherapist specialising in backs, and for a referral to a spine surgeon when symptoms limit life despite training.
Exercises for spinal stenosis: forward-bent position, core strength and fitness
The principle is to train in positions that widen the canal (flexed lower back) and avoid positions that compress it (arching, bending backwards), to strengthen the core and buttocks so the back is held stable with less arch, and to keep up fitness with training that works: cycling, water walking, walking training with breaks. Ten to fifteen minutes daily plus fitness three times a week.
- Knee to chest: on your back, pull one knee to the chest, hold 20–30 seconds, switch; then both knees, 30 seconds, 3 times. Opens the canal and loosens the lower back; good as a morning exercise and as a break on a walk (sitting on a bench and bending forward does the same).
- Pelvic tilt: on your back with bent knees, flatten the lower back against the floor, hold 5 seconds, 10–15 times. Teaches the position that offloads; use it standing too.
- Cat (without cow): on all fours, round the back up towards the ceiling, hold 5 seconds, return to neutral (not arched), 10 times.
- Seated forward fold: sit on a chair, let the upper body fall forward between the knees, hands towards the floor, 30 seconds, 3 times. Quick relief when the legs have gone numb.
- Dead bug: on your back, lower back flat, extend opposite arm and leg without the lower back lifting, 8–10 per side. Core strength without load on the canal.
- Glute bridge: on your back with bent knees, lift the hips until the body is straight from knee to shoulder, no higher (no arch), 2 × 12. Strong glutes reduce the arch when standing.
- Kneeling hip flexor stretch: but only as far as the arch doesn't increase; draw in the navel and tilt the pelvis backwards during the stretch, 30 seconds per side. Short hip flexors pull the back into an arch.
- Cycle 20–30 minutes, stationary or ordinary bike with a slight forward lean, three to five times a week: fitness is preserved in a position the back likes.
- Walking training with breaks: walk until the symptoms start to come, sit down or bend forward for 30–60 seconds until they release, walk again. 20–30 minutes in total. Poles or a rollator with a seat extend the distance noticeably because you can lean forward; a shopping trolley too. A treadmill with an uphill incline and support on the handles works well.
- Water aerobics and swimming (breaststroke with the head above the surface increases the arch; crawl or backstroke is better).
Avoid long back bends, standing rotations with weight, long periods standing still, hard mattresses that increase the arch, and "walking through" the symptoms: when the legs go numb you should bend, not fight. More exercises in lower back stretches and core exercises.
What you can do yourself in daily life
- Sleep on your side with a pillow between the knees or on your back with a pillow under the knees (flexed lower back); not on your front.
- Stand with one foot on a low stool (widens the canal), switch feet; lean against the counter when you wash up.
- Sit by all means, but get up and walk for short spells; a slightly forward-leaning sitting position is best, a too-low sofa is worst to get up from.
- Weight: a few kilos less around the belly reduces the arch and the load noticeably.
- Pain relief: paracetamol in courses, anti-inflammatories for short periods if stomach and kidneys allow, medicines for nerve pain (gabapentin, pregabalin, duloxetine) via a doctor for numbness and night symptoms; a cortisone injection into the spinal canal can give relief for weeks to months and be used to get going with the training. Opioids have poor effect in stenosis and should be avoided.
- Keep going: inactivity makes the legs weaker and the symptoms worse; those who train regularly keep their walking distance better over the years.
When surgery is needed, and what it gives
Surgery (decompression, where what is pressing is removed: ligament, bone, sometimes disc, sometimes with fusion if the vertebrae are unstable) is considered when walking distance and daily life are seriously limited despite three to six months of proper training, when numbness or weakness increases, or with bladder and bowel involvement (then urgently). Studies show that those operated get better walking ability and less leg pain than those not operated during the first two years, that the difference then decreases, and that the back pain doesn't always improve. About 70–80 per cent are satisfied; risks are infection, bleeding, nerve involvement and recurrence at another level. Rehab after surgery: walks from day one, core training after six weeks, full activity after three months. You can say no to surgery and continue with training: stenosis rarely leads to paralysis, and many remain stable in their symptoms for years.
Cupping for spinal stenosis
Cupping doesn't affect the narrowing, which sits in bone and ligament, but it makes a clear difference to what is often half of the problem: the muscles of the lower back, buttocks and thighs, which in stenosis are chronically tense from the protective posture, and which give the back pain, hip stiffness and morning stiffness that aren't due to the nerves. Relaxed muscles also make it easier to hold the backward-tilted pelvic position that widens the canal. How to: lie on your front with a pillow under the belly (flexed lower back, comfortable position) or sit backwards on a chair leaning forward over the backrest. Oil the skin. Glide the dynamic cup with light to moderate suction along the muscles on each side of the lower back, from the pelvis up towards the ribs, ten strokes per side, never on the vertebrae themselves and never with strong suction over an operated back; then over the buttocks in circles and from the buttock down along the back and outside of the thigh, ten strokes per leg (the muscles that pull on the pelvis). Then place static cups with light to moderate suction on each side of the lower back at belt level and on the buttock muscles, five to ten minutes while you breathe out calmly. Finish with knee to chest and pelvic tilt. Three to four times a week, the evening is good. Don't cup with new numbness or weakness that should be assessed, not over a fresh surgical scar (wait six to eight weeks and ask the surgeon), not with fever or on blood thinners without the doctor's go-ahead, and expect relieved muscle ache, not a longer walking distance: that comes from the training. More in lower back pain and cupping at home.

Frequently asked questions
How does spinal stenosis feel?
Heaviness, numbness, weakness or ache in buttocks, thighs and lower legs, often both sides, that comes when you have walked or stood upright for a while and forces you to stop, and that releases when you bend forward, sit down or cycle. Many walk leaning forward, manage the shopping trolley but not the walk, and rest by sitting, not standing still. Back pain is often present but doesn't dominate. Most common after 60. Walking distance varies from day to day and is shorter downhill.
What is the difference between spinal stenosis and sciatica?
Sciatica (usually a herniated disc) gives a sharp pain in one leg down to the foot, worse with sitting, bending forward and coughing, better with walking and lying down, most common at 30–50. Stenosis gives heaviness and numbness in both legs when you walk and stand, better with bending forward and sitting, most common after 60. Vascular claudication resembles stenosis but releases with standing still in any position and gives the same walking distance every time.
Which exercises help spinal stenosis?
Exercises in a forward-bent position that widen the canal (knee to chest, pelvic tilt, cat, seated forward fold), core strength without arching (dead bug, glute bridge), hip flexor stretch with the pelvis tilted backwards, cycling 20–30 minutes and walking training with forward-bent breaks. Avoid back bends, long periods standing and walking through the symptoms. Ten to fifteen minutes daily plus fitness three times a week.
Do you have to operate on spinal stenosis?
No, most don't need to: stenosis rarely leads to paralysis and many remain stable in their symptoms for years with training. Surgery is considered when walking distance and daily life are seriously limited despite three to six months of proper training, when numbness and weakness increase, or urgently with bladder and bowel involvement. Those operated get better walking ability in the first years; the back pain doesn't always improve, and 70–80 per cent are satisfied.
Does cupping help spinal stenosis?
Not the narrowing itself, but the tense muscles in lower back, buttocks and thighs that account for a large part of the back pain and stiffness, and it makes it easier to hold the pelvic position that widens the canal. The dynamic cup along the lower back muscles, over the buttocks and the back of the thighs, then static cups on lower back and buttocks for five to ten minutes, three to four times a week, followed by knee to chest. Not over the vertebrae, not over a fresh surgical scar, not with new numbness or weakness that should be assessed.
