Massage for sciatica

Why it happens

The sciatic nerve is the largest nerve in the body. It forms from nerve roots that leave the lower spine, passes through the buttock under the gluteal muscles, and runs down the back of the thigh toward the foot. When something irritates it anywhere along that path, you feel it along the path: a deep ache in the buttock, a burning or electric line down the back of the leg, sometimes tingling or numbness in the calf or foot.

“Sciatica” describes where the pain goes, not what causes it. The spine is the most common source. The hip is a less common one, and the two can overlap.

At the spine. A disc between two vertebrae in the lower back bulges and presses on a nerve root, or the space around the root narrows with age. Pain is often worse with sitting, bending forward, coughing or sneezing, and it may reach below the knee. Most of this kind settles gradually over weeks to a few months, as the irritated root calms down.

In the hip. The piriformis and the other deep rotators of the hip sit right next to the sciatic nerve, and in some people the nerve runs through them. When these muscles are tight, overworked or in spasm, they can press on the nerve or irritate it. Sitting on a wallet, long drives, running, and sitting cross-legged for hours all load them. Pain is usually centered in the buttock and worse with sitting.

Tender spots in the gluteal muscles can also send an ache down the back of the thigh that feels like sciatica without the nerve being involved at all.

Whatever the source, the muscles of the low back and hip often tighten around the irritated area to protect it. That guarding makes you move less, and moving less makes the stiffness worse.

What massage can do about it

Massage can do a good deal about the muscle part of sciatica and very little about the disc part. It is worth being clear which is which.

What it can ease:

• Tight gluteal and deep hip muscles that may press on or irritate the nerve. Slow pressure on the piriformis and its neighbors sometimes brings on the familiar deep ache in the buttock, which suggests the muscle may be part of it. If the feeling turns sharp or electric, or shoots down the leg, I ease off at once.
• Guarding in the low back and hips that has built up around the pain.
• Stiffness in the hamstrings and hip flexors that changes how you sit, stand and walk.

What it cannot do: move a disc back into place, widen a narrowed space in the spine, or speed up how fast an irritated nerve root settles. If your pain comes mainly from the spine, massage can make the weeks of recovery more comfortable, but it will not shorten them by itself.

For most people the work is deep tissue massage on the hip and low back, done slowly. A nerve that is already irritated does not like fast or aggressive pressure. A dull, deep ache in the muscle is fine to work with; sharp or electric nerve sensations are not. If the leg pain is part of a wider pattern in the back and hips, therapeutic massage covers more ground.

When the hip muscles are a large part of the problem, many people notice a change within the first few sessions. If three or four visits bring no change, that is a good reason to have a doctor look at your lower back. The broader picture of back pain is under lower back pain.

What my physical-therapy training adds

My physical-therapy training from Ukraine matters most here, because the first job is to work out, as far as a massage therapist can, where the leg pain seems to start.

I ask what makes it worse: sitting, bending, coughing, walking, lying on one side. I watch you bend and move your hips, and I compare how the two sides rotate. Pain that is reproduced by pressing on the hip muscles points one way. Pain that changes with movements of the spine points another.

I explain what I find plainly. If the picture suggests the problem sits in the spine rather than the hip, I will tell you, and I will suggest you see a doctor before we go further.

Between sessions, you get gentle exercises to keep the hip and low back moving without provoking the nerve. For irritated nerves, the right exercise done gently beats a hard stretch done once.

When to see a doctor first

Sciatica-type pain is common and usually not dangerous, but a few signs mean the nerve roots are under serious pressure. Go to the emergency department immediately if you have:

• Numbness in the groin, genitals, buttocks or inner thighs, the area that would touch a saddle.
• New loss of bladder or bowel control, or you cannot pass urine.
• Leg weakness that is getting worse, such as a foot that drags or slaps when you walk.
• Pain or numbness in both legs, or new sexual problems, together with back pain.

See a doctor before booking a massage if the pain started after a fall or accident, comes with fever or weight loss you cannot explain, or has not improved at all after several weeks. A swollen, warm, tender calf with the pain can mean a blood clot. Go to the emergency department, and do not have it massaged.

Massage therapy is not medical care.
