What is Sciatica?
Short Answer
Sciatica is a term commonly used to describe pain, tingling, numbness, or other symptoms that travel from the low back or buttock into the leg, often following the path of the sciatic nerve.
Sciatica is not actually a diagnosis itself. It is a description of a symptom pattern. Several different conditions can contribute to sciatic symptoms, which is why an assessment is often important. Dr. Ethan Marler, Chiropractor, takes a function-focused approach to understanding what may be contributing to symptoms and helping patients return to the activities that matter to them.
Why This Question Matters
The sciatic nerve is the largest nerve in the body.
It begins in the lower back and travels through the buttock and down the leg. Symptoms can occur when the nerve becomes irritated, compressed, sensitized, or affected somewhere along its pathway.
Common contributors may include:
Disc-related irritation in the low back
Narrowing around the spaces where nerves travel
Joint-related irritation
Muscle-related irritation around the hip or buttock
Reduced tolerance to certain positions or movements
Previous injuries
Changes in activity levels or workload
Sciatic symptoms can vary significantly from person to person.
Some people experience a sharp, shooting pain down the leg. Others notice tingling, numbness, burning, weakness, or discomfort that extends below the knee.
Not every case of leg pain is sciatica, and not every case of sciatica is caused by the same thing. This is one reason a thorough assessment can be valuable.
What May Help
Many people with sciatica notice that symptoms change depending on position, movement, or activity levels.
General strategies that may help include:
Staying as active as symptoms reasonably allow
Avoiding prolonged positions that consistently aggravate symptoms
Taking movement breaks throughout the day
Gradually returning to normal activities when possible
Paying attention to patterns that seem to increase or decrease symptoms
For some people, complete rest may not be the most helpful approach. Gentle movement and gradual exposure to activity are often important parts of recovery.
If symptoms are severe, worsening, or limiting daily activities, professional assessment may be appropriate.
Dr. Marler’s Approach
Dr. Marler views sciatica as a symptom pattern rather than a diagnosis.
His goal is to understand why the symptoms are occurring and what may be contributing to them.
Depending on the individual, assessment may include:
Low back function
Hip mobility
Movement tolerance
Nerve-related symptoms
Activity demands
Work requirements
Previous injury history
Functional limitations
Treatment may include chiropractic adjustments when appropriate, soft tissue therapy, movement recommendations, rehabilitation strategies, and patient education.
The focus is not simply on reducing symptoms. The goal is to improve function, build confidence, and help patients return to meaningful activities as safely and comfortably as possible.
When to get Assessed
It may be worth booking an assessment if:
Pain is travelling into the buttock or leg
Symptoms extend below the knee
Numbness or tingling is present
Symptoms are affecting walking, sitting, sleeping, or work
Symptoms are not improving
Symptoms repeatedly return
When to Seek Urgent Medical Care
Seek immediate medical attention if symptoms are accompanied by:
Loss of bowel or bladder control
Numbness in the groin or saddle area
Significant or worsening leg weakness
Difficulty walking due to severe weakness
Major trauma
Other serious neurological symptoms
These situations require urgent medical assessment.
Frequently asked questions
-
Sometimes, but not always.
Sciatica is commonly associated with irritation or sensitivity involving the sciatic nerve, and a pinched nerve is one possible cause. However, the term "sciatica" actually describes a pattern of symptoms rather than a specific diagnosis.
People with sciatica may experience:
Pain travelling down the leg
Tingling
Numbness
Burning sensations
Weakness in some cases
While a disc injury can sometimes contribute to nerve irritation, not every case of sciatica is caused by a pinched nerve. Different structures and conditions can produce similar symptoms.
Dr. Marler often focuses on understanding how symptoms behave, where they travel, and what activities influence them rather than assuming there is a single cause. This helps guide appropriate recommendations and determine whether further investigation may be necessary.
-
Yes.
Many cases of sciatica improve over time without surgery or invasive treatment. The body often has a remarkable ability to recover, particularly when people remain appropriately active and continue participating in daily activities as tolerated.
That said, recovery timelines vary considerably. Some people improve relatively quickly, while others experience symptoms for a longer period.
Factors that may influence recovery include:
Symptom severity
Activity levels
Overall health
Previous episodes
Work and lifestyle demands
Dr. Marler often helps patients understand what activities may be appropriate during recovery and how to gradually build tolerance to movement and daily tasks.
The goal is not simply to wait for symptoms to disappear but to help people remain active and confident while recovery occurs.
-
Sciatica travels down the leg because the sciatic nerve extends from the lower back through the buttock and into the leg.
When the nerve becomes irritated or sensitive, symptoms may be felt anywhere along its pathway.
People commonly describe:
Pain in the buttock
Pain in the back of the thigh
Tingling below the knee
Symptoms reaching the calf or foot
Burning or electric-like sensations
The location of symptoms can vary from person to person and may even change over time.
Dr. Marler often explains that the pattern of symptoms can provide useful information during an assessment. Understanding where symptoms travel and what activities influence them can help identify what may be contributing to the problem and guide appropriate management strategies.
-
For many people, yes.
Walking is often a well-tolerated form of activity that allows people to remain active without placing excessive demands on the body.
Potential benefits may include:
Maintaining mobility
Promoting circulation
Reducing fear of movement
Supporting overall activity levels
However, not everyone responds the same way. Some people feel better with walking, while others may notice symptoms increase depending on the nature of their condition.
Dr. Marler typically encourages patients to focus on what activities they can tolerate rather than avoiding movement altogether. Walking is often a useful starting point because it is accessible, easy to modify, and can help maintain confidence during recovery.
The goal is to remain as active as reasonably possible while respecting symptom behaviour.
-
Most cases of sciatica improve without serious complications, but certain symptoms require prompt medical attention.
Seek immediate medical assessment if you experience:
Progressive weakness in the leg
Loss of bowel or bladder control
Significant loss of sensation
Numbness in the groin or saddle area
Severe or rapidly worsening symptoms
It may also be worth seeking assessment if symptoms are:
Persisting longer than expected
Significantly limiting daily activities
Preventing work or exercise
Repeatedly recurring
Dr. Marler often helps patients understand which symptoms are common, which symptoms may require further investigation, and how to safely return to meaningful activities while managing sciatica.
The goal is to provide reassurance when appropriate while recognizing situations that warrant additional medical evaluation.
