Not sure if it’s sciatica, a herniated disc, or SI joint pain? Learn key signs, simple self-checks, and when to see a Coral Springs chiropractor.
Lower back and leg pain can wear anyone down. Three common culprits—sciatica, a herniated disc, and SI (sacroiliac) joint pain—often look similar at first glance. The good news: each has a pattern. Below is a simple, evidence-aligned guide to help tell them apart, what to try first at home, and when to see a Coral Springs chiropractor for targeted care.
Quick symptoms at a glance
| Sign / Symptom | Sciatica (nerve irritation) |
Herniated Disc (disc material pressing a nerve) |
SI Joint Pain (pelvis joint) |
|---|---|---|---|
| Pain path | Back/buttock → down the leg, sometimes to foot | Back pain first; leg pain follows, often one side | Low back/buttock, often one side; may refer to groin or thigh (not usually below knee) |
| Numbness/tingling | Common, follows a narrow line | Common; may include weakness in ankle/toes | Less common; more “achey” or sharp near dimple of back |
| Worse with | Sitting long, bending, coughing/sneezing | Sitting, bending, lifting; morning stiffness | Standing from sitting, rolling in bed, stairs, single-leg loading |
| Better with | Short walks, gentle nerve glides | Gentle extension-based movement, unloading | Supported sitting, belt/bracing temporarily, hip/glute activation |
Note: These are patterns, not diagnoses. Red-flag symptoms below require urgent care.
Simple at-home checks (easy and safe)
Stop if pain is sharp, spreading, or worrisome. These are screens, not DIY fixes.
-
Seated “slump-lite” check (nerve irritation):
Sit tall, extend one knee slightly, flex ankle (toes up). If that reproduces a familiar line of leg symptoms that ease when bending the knee back down, it suggests nerve tension consistent with sciatica. -
Prone press-ups (disc loading screen):
Lie face down, prop on forearms. If that eases leg symptoms or centralizes pain toward the low back, a disc component may be involved. If pain shoots worse down the leg—stop. -
Single-leg load (SI joint bias):
Stand tall, shift weight to one leg and gently hinge a few inches. Localized pain near the back “dimple” or at the top of the buttock—especially when transitioning sit↔stand—leans SI joint.
These checks don’t replace an exam, but they can help steer the next step.
Red flags — seek urgent medical care now
-
New or worsening numbness in the saddle area
-
Loss of bowel or bladder control, or inability to urinate
-
Progressive leg weakness or foot drop
-
Fever or unexplained weight loss with back pain
-
History of cancer, recent major trauma, or infection risk
If any of these apply, go to urgent care or the ER.
What helps — care that matches the cause
At Champion Chiropractic in Coral Springs, plans are individualized, but here’s how we typically approach each pattern:
-
Sciatica / nerve irritation
-
Reduce mechanical irritation (positioning changes, activity tweaks)
-
Chiropractic adjustments and mobilization to improve segment motion
-
Gentle nerve glides, hip mobility, core stability
-
Short walks over long sitting; gradual return to loading
-
-
Herniated disc patterns
-
Positions that centralize symptoms (often extension-biased)
-
Flexion-distraction and spinal decompression when appropriate
-
Education on lifting strategy and pacing (your spine loves consistency)
-
-
SI joint pain
-
Targeted adjustments or mobilization for the SI complex
-
Glute/hamstring activation, anti-rotation core work
-
Short-term support (taping or an SI belt) during flare-ups
-
Gait and posture coaching; load management for stairs/single-leg tasks
-
Care is always scaled to the person in front of us—athletes, desk pros, weekend warriors, new parents carrying car seats. No cookie cutters, just patterns plus progressions.
When to get checked in Coral Springs
If pain has persisted longer than 7–10 days, is interrupting sleep, or you’re unsure which pattern fits, an in-person exam can save weeks of guessing. A focused evaluation can rule out red flags, identify aggravators, and build a plan you can follow with confidence.

FAQ
Is sciatica the same as a herniated disc?
Not always. A herniated disc can cause sciatica, but sciatica simply means irritation of the sciatic nerve. Other sources (like tight spaces around the nerve) can mimic it.
Do I need an MRI for leg pain?
Not usually at first. Most cases improve with a thorough assessment and conservative care. Imaging is considered for red flags, severe or progressive weakness, or lack of improvement over time.
Can SI joint pain cause numbness?
It typically causes localized pain near the back of the pelvis. True numbness/tingling down the leg suggests nerve involvement—get evaluated.
