The first weeks matter
Acute nerve pain has a window. Addressed early, most sciatica settles within weeks. Left to run, the body builds compensation patterns that can turn an acute problem into a chronic one.
I see this constantly. Someone tweaks their back lifting firewood, sitting too long on a rough drive over the Kootenay Pass, or pushing through one ski day too many at Whitewater. The pain shoots down the leg. They wait, hoping it resolves. By the time they come in — weeks later — they are limping, sleeping badly, and bracing every time they stand up.
Good news: sciatica responds well to skilled manual therapy. Meta-analyses of osteopathic manipulative treatment for low back and sciatic pain show meaningful, durable reductions in pain — benefits that hold at three months and beyond. Timing matters, and so does approach.
Sciatica is a symptom, not a diagnosis

"Sciatica" is the name we give to pain that travels along the sciatic nerve — the longest nerve in the body, which begins in the lower back, passes through the buttock, and runs down the back of each leg. When something irritates, compresses, or inflames that nerve anywhere along its path, you feel it as sciatic pain.
That distinction matters because the cause changes the treatment. Someone with a bulging disc and someone with a tight piriformis both have "sciatica," but they need quite different work.
The typical picture: sharp, shooting pain down one leg, often with burning or tingling along the back of the thigh or calf, sometimes numbness or weakness, worse with sitting, coughing, or bending forward. Pain is usually one-sided. It can be constant or intermittent.
The common causes
- Herniated or bulging disc. What most people picture. Disc material presses on a nerve root, and the inflammatory response adds to the irritation.
- Piriformis syndrome. The piriformis is a small muscle deep in the buttock. The sciatic nerve runs underneath it — and in some people, right through it. When it tightens, the nerve gets compressed. Symptoms can look almost identical to disc-related sciatica.
- Spinal stenosis. Narrowing of the spinal canal, more common with age, reducing the space available for the nerve roots.
- Degenerative disc disease. Age-related wear that thins the discs and changes how forces travel through the spine.
- Less commonly, spondylolisthesis, pregnancy-related pelvic changes, trauma, and — rarely — causes that need medical workup.
"Sciatica is rarely about the nerve alone. It's about everything around the nerve that has been pulling, pressing, or compensating for a long time before the symptoms started."
The visceral connection most people don't know about
Here is something most patients — and many practitioners — don't consider: the internal organs can influence sciatic pain.
The psoas muscle, the body's primary hip flexor and a major contributor to lumbar stability, runs directly alongside the kidneys. The kidneys themselves sit on a layer of fascia that connects into the lumbar region. When a kidney is restricted in its normal slight movement — from old infections, scar tissue, chronic dehydration, or simply postural patterns — the surrounding fascia can pull on the psoas, change pelvic mechanics, and contribute to nerve irritation.
This isn't theoretical. It's something you can feel with trained hands and treat with gentle visceral manipulation — techniques I learned through advanced training with Frank Lowen. More than a few patients have come in convinced their problem was "a disc" and left, after a few sessions, having discovered the real driver was a stuck kidney or a restricted colon changing how the pelvis moved.
Recovery phases
Acute (0–2 weeks). The loudest phase. Pain is intense, inflammation is peaking. The goal isn't to push, stretch hard, or work through it — it's to calm things down. Gentle soft-tissue work, careful joint mobilization, positional release, and specific home positions that take pressure off the nerve.
Subacute (2–6 weeks). Pain decreasing but not gone. The nerve is healing. This is the phase where compensation patterns either get addressed or quietly become permanent. Work moves toward restoring normal movement, hip mechanics, and whatever the original drivers turned out to be.
Recovery (6–12 weeks). Pain minimal or gone. Work shifts from symptom management to prevention — making sure the foundation is solid so the pattern doesn't rebuild.
Chronic (beyond 12 weeks). Not hopeless. Chronic nerve pain often involves central sensitization — the nervous system becoming more reactive — and treatment takes longer and works on multiple layers. Even patients with years of sciatica often see meaningful improvement.
How I treat it
Treatment draws on a wide toolkit. The right combination depends on the person. In practice that usually means some of: soft-tissue and myofascial release to reduce guarding in the glutes, piriformis, hamstrings, and quadratus lumborum; gentle joint mobilization for the lumbar spine, sacroiliac joints, and hips; visceral manipulation when assessment points there; biodynamic craniosacral work to address dural tension and settle the nervous system; and — once the acute irritation has settled — nerve mobilization to improve how the nerve glides through surrounding tissues.
I don't use aggressive high-velocity manipulation on acute sciatica. Treatment shouldn't increase your sciatic pain. If something does during a session, we change what we're doing. The body doesn't heal under force.
⚠ When to Seek Immediate Care
- Loss of bowel or bladder control
- Numbness in the saddle region — inner thighs, groin, or genitals
- Progressive weakness, or new foot drop (inability to lift the front of the foot)
- Severe sciatica following significant trauma
- Sciatica with fever, unexplained weight loss, or night pain that wakes you
- Sudden severe symptoms in *both* legs
