Sciatica & Nerve-Related Symptoms
Sciatica refers to irritation or compression of the sciatic nerve, which can cause pain and nerve-related symptoms that travel from the lower back into the buttock, thigh, and sometimes below the knee into the foot. It is one of the most common causes of radiating leg pain.
At Physio Elements Kilsyth, we assess, diagnose, and treat sciatica and nerve-related symptoms using evidence-based physiotherapy focused on reducing nerve irritation, improving movement, and restoring function.
Early assessment is important to identify the cause and guide safe and effective recovery.
What Is Sciatica?
What does sciatica mean?
Sciatica is a term used to describe symptoms caused by irritation or compression of the sciatic nerve. It is not a diagnosis on its own, but a presentation of underlying nerve irritation in the lower back.
It commonly results in pain, tingling, or altered sensation that travels along the path of the nerve
down the leg.
What Causes Sciatica?
Why does sciatic nerve pain happen?
Sciatica commonly develops from:
- Disc bulge or disc herniation
- Spinal joint irritation or inflammation
- Tight or overactive surrounding muscles
- Poor spinal posture or prolonged sitting
- Repetitive bending or lifting
- Reduced core and spinal stability
- Nerve root irritation in the lower back
In most cases, symptoms are caused by nerve irritation rather than permanent nerve damage.
Symptoms of Sciatica
What does sciatica feel like?
Common symptoms include:
- Sharp, shooting pain from lower back into the leg
- Pain in the buttock, thigh, calf, or foot
- Tingling or “pins and needles” sensation
- Numbness or reduced sensation in the leg
- Burning or electric-like nerve pain
- Pain that worsens with sitting, bending, or coughing
- Weakness in the leg (in some cases)
Symptoms may vary depending on the level of nerve irritation.
When Should You See a Physiotherapist?
Do I need physiotherapy for sciatica?
You should see a physiotherapist if:
- Pain is radiating into the leg
- Symptoms are persistent or worsening
- You have tingling, numbness, or nerve pain
- Movement is becoming limited or painful
- Symptoms are affecting sleep, work, or daily activity
- You want a structured recovery plan
When should I seek urgent medical attention?
Seek urgent medical attention if you experience:
- Loss of bladder or bowel control
- Numbness in the groin or saddle area
- Significant or rapidly worsening leg weakness
- Severe pain following trauma
How Physiotherapy Helps Sciatica
How is sciatica treated?
Physiotherapy for sciatica focuses on reducing nerve irritation, improving movement, and restoring
normal function.
Treatment may include:
- Comprehensive neurological and spinal assessment
- Pain relief strategies and activity modification
- Nerve mobility (neural glide) exercises
- Directional movement exercises for symptom relief
- Core and glute strengthening
- Spinal mobility and stability training
- Soft tissue release for surrounding muscles
- Postural and ergonomic correction
- Education on flare-up management and load control
This approach helps reduce nerve sensitivity and supports long-term recovery.
Recovery and Outlook
How long does sciatica take to improve?
Recovery varies depending on the cause and severity:
- Mild nerve irritation: a few days to 2–4 weeks
- Moderate cases: 4–8 weeks
- More persistent cases: longer-term rehabilitation may be required
Most cases improve significantly with physiotherapy and gradual return to movement.
