If you have sciatica, you have probably already been given two different answers by two different people. One friend swears her chiropractor fixed it. Another says physical therapy was the only thing that worked for him. Both are telling the truth. The useful question is not which profession is better. It is which one fits your sciatica, at the stage you are in right now.
I have practiced chiropractic in Cambridge for more than 40 years, and I refer patients to physical therapists every month. This is the conversation I have with people who call the office unsure where to start. If you want the broad overview of chiropractic, physical therapy and massage, read that comparison. This post is only about sciatica, and it is meant to help you make a decision.
Sciatica Is a Symptom, Not a Diagnosis
Sciatica means pain that travels along the sciatic nerve, from the low back or buttock down the back of the leg, sometimes into the foot. It is caused by something irritating the nerve or the nerve roots that form it. The most common cause is a lumbar disc bulge or herniation. Other causes include spinal stenosis, a slipped vertebra, or a tight piriformis muscle pressing on the nerve in the buttock. I cover the causes in detail in Understanding Sciatica and the muscle version in Piriformis Syndrome vs Sciatica.
The cause matters here because it drives the choice. A fresh disc herniation and a deconditioned back that flares every winter are both called sciatica, and they do best with different approaches.
What a Chiropractor Does for Sciatica
My first job is diagnosis. That means a history, orthopedic tests such as the straight leg raise, reflex and sensation testing, and a referral for an MRI when the exam calls for it. Then treatment, which in my office is hands-on first:
- Spinal manipulation. Restoring motion to restricted lumbar and pelvic joints, which reduces mechanical load on the irritated nerve root. For disc cases I use gentle, low-force methods rather than a forceful twist.
- Spinal decompression. Computer-controlled intermittent traction on a table, 15 to 30 minutes a session, to reduce pressure inside the disc. A typical course is 12 to 20 sessions over about six weeks.
- Soft tissue work. Active Release Technique on the piriformis, glutes and hamstrings, which are almost always guarding by the time someone walks in.
- Home exercise. Two or three movements, not a binder. The goal early on is to find the positions that pull pain out of the leg and back toward the spine.
What a Physical Therapist Does for Sciatica
A physical therapist starts with a movement assessment: how you bend, sit, stand and walk, and which directions make the leg pain better or worse. From there the work is exercise progression and movement retraining. Early on that often means repeated movements in a direction that centralizes the pain, nerve gliding, and a walking program. Later it means hip and trunk strengthening, retraining how you lift and sit, and a graded return to running, cycling or whatever you want back. Many physical therapists also do manual therapy, including joint mobilization and soft tissue work, though exercise remains the backbone.
I want to be fair about this: for the right patient, a good physical therapist's exercise program is the treatment, not an add-on. I have sent plenty of people down the street and been glad I did.
Where the Two Overlap
Both professions diagnose, both use their hands, both prescribe home exercise, and both will tell you how to sit and sleep. The difference is emphasis and sequence. Chiropractic is hands-on treatment first, with exercise supporting it. Physical therapy is exercise first, with hands-on work supporting it. Good practitioners on both sides borrow from each other, which is why the question can feel confusing.
Which Presentations Tend to Do Better Where
Acute, Disc-Driven Pain With a Mechanical Pattern
The pain started days or a few weeks ago. It is clearly worse with sitting, bending or coughing and better standing or walking. Certain positions shift the pain up the leg or down it. This is the patient I think does best starting with chiropractic care. In the acute phase, exercise tolerance is low, and manipulation, decompression and soft tissue work can reduce pain enough that movement becomes possible. Once the leg pain is centralizing, exercise takes over.
Chronic, Recurrent or Deconditioned Cases
Sciatica that has come and gone for years, weak hips and trunk, fear of bending, and a desk job in Kendall Square that keeps you seated ten hours a day. I still treat these patients, and adjustments help them feel better, but the fix is capacity. A structured physical therapy progression is the right backbone here, and I say so at the first visit.
Post-Surgical Cases
After a microdiscectomy, laminectomy or fusion, physical therapy comes first. The surgeon's protocol governs the timeline, and a physical therapist is trained to work inside it. I see post-surgical patients later, if at all, and only with the surgeon's clearance.
Stenosis in Older Adults
Leg pain that comes on with walking and eases when you sit or lean on a shopping cart is usually stenosis, not a disc. These patients often do well with a combination: gentle manipulation and flexion-based decompression from me, plus a physical therapist's walking and strength program.
The Case for Doing Both
This is not an either-or choice, and the best outcomes I see often involve both offices. The usual sequence is chiropractic care early to reduce pain and restore joint motion, then physical therapy to build the strength that keeps it from coming back. Some patients do both at the same time. When that happens I write a note to the physical therapist so we are not duplicating work, and so you are not paying two providers for the same exercise sheet.
Referrals, Direct Access and Insurance in Massachusetts
Massachusetts allows direct access to chiropractic care, so you do not need a referral to see me. Physical therapy is also direct access in Massachusetts for most situations. The catch is the insurance plan: some plans still require a physician referral or prior authorization before they will pay for physical therapy, and a few treat chiropractic the same way. Check your plan before the first visit.
On cost, both are usually covered as specialist visits, but copays and visit limits vary by plan. Some plans count chiropractic and physical therapy against the same annual visit limit, others keep them separate. I am not going to quote a copay here because yours depends on your plan. We verify benefits before treatment so you know what you owe, and our insurance page explains how that works.
What to Expect in the First Two Weeks
With a Chiropractor
The first visit is a history, an exam and, in most cases, a first treatment the same day. Early visits are two to three a week. You leave each visit with two or three home movements and clear instructions on what to avoid. By the fourth to sixth visit you and I should both know whether this is working, which usually shows up as leg pain retreating toward the back before the back pain itself fades.
With a Physical Therapist
The first visit is an evaluation, usually longer than a treatment visit. Expect one to two visits a week and daily homework between them. The first two weeks are mostly finding your directional preference, nerve glides and a walking program. Progress is measured by function: how long you can sit, how far you can walk, how your leg feels after.
When Neither Is the Right First Call
Some sciatica needs a physician or an emergency department before it needs either of us:
- Progressive weakness in the leg or foot, including a foot that slaps or drags
- Any change in bowel or bladder control, or numbness in the groin or inner thighs
- Fever with back pain, unexplained weight loss, or a history of cancer
- Pain that began with major trauma
- Severe pain that does not change with any position and wakes you every night
Also: if a fair trial of four to six weeks with either profession has produced no change, it is time for imaging and a spine specialist consultation, not a seventh week of the same thing.
My Honest Recommendation
Start with whichever provider can examine you soonest, as long as that provider will tell you plainly if you are in the wrong place. In my office, that is part of the first visit. If the exam says you belong with a physical therapist or a surgeon, I will say so and help you get there. If you would like that evaluation, learn more about how we treat sciatica and leg pain or call (617) 494-1166. We hold same-day slots for patients in pain.
