What Sciatica Is and Why It Happens

Sciatica is the name for a symptom. It describes pain, tingling, numbness or weakness that follows the path of the sciatic nerve, which is formed by nerve roots in the lower spine and runs through the buttock and down the back of each leg. The pain usually affects one side and can reach the calf or foot. Sitting, coughing or bending forward often makes it worse.

Most sciatica comes from irritation of a nerve root where it leaves the lower spine. Common causes include a bulging or herniated disc, narrowing of the spinal canal (spinal stenosis), a vertebra that has slipped forward on the one below it (spondylolisthesis), and wear in the joints and discs that comes with age. Tightness in the piriformis muscle of the buttock can produce similar pain by irritating the nerve after it leaves the spine, and our guide to piriformis syndrome vs. sciatica explains how to tell them apart.

Because several different problems produce the same leg pain, finding the source matters more than naming the symptom. Care that fits a disc problem is not the same as care that fits a stiff joint or a tight muscle, so the evaluation comes first.

How Sciatica Is Evaluated at Heem Health

Your first visit is an evaluation. Dr. Park takes a history of where the pain travels, when it started, what makes it better or worse and what you have already tried. The exam looks at how you bend, sit, stand and walk, tests the strength, reflexes and sensation in the leg, and uses movement tests that load the nerve to confirm that the sciatic nerve is the source.

When the findings call for it, in-motion DDR X-ray records the lower spine as you bend and straighten. A still X-ray shows one position. Motion X-ray shows how each segment moves through the range, which can reveal a level that shifts too much or too little and is not obvious on a static image. Imaging is used when it is expected to change the plan, not as a routine step.

You will hear what was found and what is proposed before any treatment starts. If the exam points to a problem that chiropractic care does not fit, Dr. Park will say so and direct you to the right provider.

Chiropractic Treatment for Sciatica

A plan for sciatica at Heem Health is built around the cause found in your evaluation and usually combines several elements.

• Chiropractic adjustments restore motion to lower spine and pelvic joints that are moving poorly, which can reduce mechanical stress on the irritated nerve root.

• Movement work retrains how you bend, lift and sit, so the spine is loaded in ways that ease the nerve rather than aggravate it. Home exercises are part of the plan.

• Supportive therapies such as laser therapy and e-stim may be added for muscle pain and tissue recovery, and shockwave therapy for tight or chronically irritated soft tissue around the hip.

Visit frequency is set after your evaluation and reviewed as you respond. Recent, mild sciatica may need a short course of care. Long-standing problems usually need more time, and the plan changes if you are not improving as expected. Our article on whether a chiropractor can help with sciatica reviews the research in plain terms.

Signs That Need a Physician First

Most sciatica improves with conservative care, but some signs call for a physician or emergency care before chiropractic treatment:

• new loss of bladder or bowel control, or numbness in the groin or inner thighs

• weakness in the leg or foot that is getting worse, such as a foot that drags or catches

• severe pain that began with a fall or accident

• pain with fever, unexplained weight loss or a history of cancer

• numbness or weakness in both legs at the same time

Dr. Park screens for these at every evaluation. If any apply, the right first step is your physician or an emergency department, and chiropractic care can follow once the cause has been cleared.

Sciatica Chiropractor FAQs

Can a Chiropractor Help With Sciatica?

Chiropractic care may help some people with sciatica, and whether it fits depends on the cause. The evaluation checks where the nerve irritation starts and screens for signs that need a physician first. Our article on whether a chiropractor can help with sciatica explains what the evidence shows.

How Long Does Sciatica Take to Improve With Chiropractic Care?

It depends on the cause, how long you have had it and how you respond. Some people notice a change within a few visits, and long-standing problems take longer. Your plan is reviewed as you go, and if you are not improving as expected, the approach changes or you are referred for further evaluation.

Is Chiropractic Care Safe for Sciatica?

For most people with sciatica, chiropractic care is a low-risk option, and the most common side effect is short-lived soreness. Your history and exam screen for conditions where adjustment is a poor fit, including the warning signs listed on this page, and those cases are referred to a physician first.

Do I Need an MRI Before Seeing a Chiropractor for Sciatica?

No. Most sciatica is evaluated by history and exam, and imaging is added when the findings call for it. Heem Health uses in-motion DDR X-ray on site when it is clinically indicated. If your exam suggests an MRI is needed, Dr. Park will refer you for one.

Does Insurance Cover Chiropractic Care for Sciatica?

Many health plans include some chiropractic coverage, and the details vary by plan. Check your deductible, copay, visit limits and whether a referral is required before your first visit. Our insurance and cost page lists what to ask.

What Is the Difference Between Sciatica and a Pinched Nerve?

Sciatica is an irritated or pinched nerve root in the lower spine that is felt along the sciatic nerve in the leg. A pinched nerve in the neck causes similar pain, tingling or weakness in the arm. Both are evaluated the same way, by finding where the irritation starts. Our guide to chiropractic care for a pinched nerve covers the neck.

The information on this page is for educational purposes and is not medical advice. If you have any of the warning signs listed above, see a physician or go to an emergency department first.
