Three sources, one symptom

Sciatica describes pain along the sciatic nerve. It does not say why the nerve is irritated, and that is the whole problem with treating it as a diagnosis.

The first source is the spine: a disc bulge or a narrowed opening pressing on a nerve root as it leaves the lower back. This is the version most people assume they have, and it is common, but it is not the only one.

The second is the facet and sacroiliac joints of the lower spine and pelvis. An irritated joint refers pain into the buttock and thigh in a pattern that can look exactly like nerve root pain at first glance.

The third is muscular. The sciatic nerve runs past, and in some people through, the piriformis deep in the buttock. When that muscle and its neighbors in the gluteal group are irritable, they can irritate the nerve directly, and their trigger points refer pain down the leg on their own, without any nerve involvement at all.

The treatment for each is different. Spine-driven sciatica responds to work at the spine and to directional loading; joint-driven pain to manipulation and mobility; muscle-driven pain to dry needling and manual work into the deep hip, followed by the strength that stops the muscle overworking. Treating all three the same way is why so much sciatica care goes nowhere.

What the examination actually does

Separating the three sources is not guesswork. Nerve tension tests, reflexes, strength and sensation testing show whether a nerve root is involved and which level. Repeated movement testing shows whether the leg pain moves toward the spine or away from it, which is the most useful single finding in planning treatment.

Palpation and provocation of the deep hip tell us whether the piriformis and gluteal muscles reproduce your pain. Joint testing of the lumbar spine and pelvis does the same for the joints.

Differential diagnosis is a core part of the post-doctorate osteopractic training, so the examination also looks for the things that are not sciatica and not a therapy problem: hip joint disease, vascular causes, and the red flags listed on this page. Imaging is rarely needed to start. Where it would change the plan, you will be told so.

Why rest and stretching keep failing

Rest calms a flare and changes nothing about why it happened. Most people are told to stretch the hamstrings, which pulls on an already irritated nerve and frequently makes things worse.

What tends to work is the opposite: finding the movement direction that centralizes the pain and doing it often, settling the irritable tissue with needling, manipulation or cupping where that is the driver, and then rebuilding the capacity of the hips and trunk so the structure that was overloaded stops being overloaded.

Sitting tolerance is usually the real-world measure. A long drive, a day at a desk, a flight. The plan is built around whichever of those your life actually contains.

Injections, surgery and when they belong

Most sciatica settles with conservative care, and most guidelines put a trial of movement-based treatment before an injection or a surgical opinion. Where there is progressive weakness, intractable pain that has not responded to a proper trial, or any of the red flags above, a physician is the right next step, and that opinion gets given plainly here rather than after months of visits.

Where therapy is the right path, it is also the one that leaves you with something: a back and hips that tolerate more than they did, and a plan for a bad week that does not involve starting over.
