Understand Your Condition
Understanding what is causing your sciatica is an important first step towards recovery. When you know what is happening, why certain symptoms occur and which activities may help, the condition often feels less frightening and more manageable.
What is sciatica?
Sciatica is not a disease in itself. It is a term used to describe symptoms caused by irritation or compression of one or more nerve roots in the lower back.
These nerves join together to form the sciatic nerve, which travels through the buttock and down the leg towards the foot.
Sciatica may cause:
- Pain travelling from the lower back or buttock into the leg
- Burning, shooting or electric-shock sensations
- Pins and needles
- Numbness
- Leg or foot weakness
- Symptoms that worsen when sitting, bending, coughing or sneezing
Back pain may also be present, although the leg symptoms can be more noticeable than the discomfort in the back.
What may be irritating the nerve?
Several different spinal conditions can produce sciatica. Common causes include:
A herniated or bulging disc
The discs sit between the vertebrae and act as cushions within the spine. If part of a disc bulges or herniates, it may irritate or compress a nearby nerve root.
Spinal stenosis
Spinal stenosis is a narrowing of the spaces through which the spinal nerves travel. Symptoms may become worse when standing or walking and improve when sitting or bending forwards.
Degenerative changes
Age-related changes can affect the discs, facet joints and surrounding ligaments. These changes may reduce the space available for a spinal nerve.
Spondylolisthesis
This occurs when one vertebra slips forwards in relation to the vertebra below it. The change in position may narrow the opening through which a nerve leaves the spine.
Inflammation around a nerve
A nerve does not always have to be severely trapped to cause symptoms. Inflammatory chemicals released from an irritated disc or surrounding tissue may make the nerve root unusually sensitive.
Understanding your individual symptoms
Sciatica affects people differently. The precise location of your symptoms can provide useful information about which nerve root may be involved.
For example, symptoms may travel into:
- The buttock
- The back or outside of the thigh
- The calf
- The shin
- The top, side or sole of the foot
- One or more toes
The pattern is not always exact. Pain, pins and needles, numbness and weakness can overlap, and symptoms may change as the nerve becomes more or less irritated.
This is why your condition should be assessed as a whole rather than diagnosed from one symptom alone.
Why a clinical assessment matters
A careful assessment helps us understand the likely source of your symptoms and identify anything requiring further investigation.
Your assessment may include:
- A detailed discussion about how the symptoms started
- Identifying where the pain or altered sensation travels
- Examining movement in the lower back and hips
- Testing muscle strength
- Checking reflexes and sensation
- Performing nerve-tension tests
- Assessing walking, balance and everyday movements
- Screening for warning signs of a more serious condition
The results allow us to explain the most likely cause of your symptoms and develop a treatment and recovery plan around your needs.
Do you always need an MRI scan?
Not everyone with sciatica needs an immediate MRI scan. In many cases, the likely cause can be identified through the history and physical examination.
An MRI may be considered when:
- Symptoms are severe or persist despite appropriate treatment
- Significant weakness or foot drop is present
- The diagnosis remains unclear
- A more serious condition needs to be excluded
- A course of IDD Therapy is being considered
- The scan result is likely to change the treatment plan
An MRI should be considered alongside your symptoms and examination findings. Changes seen on a scan do not always explain the pain, so the image should never be interpreted in isolation.
Pain does not always equal damage
Sciatica can be extremely painful, but the intensity of the pain does not necessarily show how much physical damage has occurred.
An irritated nerve can become highly sensitive. Ordinary movements, sitting positions or small increases in pressure may then produce strong symptoms. Muscles may also tighten protectively around the lower back and pelvis, making movement feel more difficult.
Understanding this can reduce some of the fear associated with movement. Your recovery plan should introduce activity gradually and at a level appropriate for your condition.
Recovery is not always a straight line
Sciatica symptoms can fluctuate. You may have several better days followed by a temporary flare-up. This does not automatically mean that you have caused further damage or returned to the beginning of your recovery.
Symptoms may be influenced by:
- An increase in activity
- Prolonged sitting
- Poor-quality sleep
- Stress or fatigue
- Lifting or repeated bending
- A long car journey
- Doing too much too quickly
Recognising your individual triggers allows activity to be adjusted without necessarily stopping altogether.
Staying involved in your recovery
Recovery is usually more effective when you understand the purpose of each part of your plan.
Depending on the cause and severity of your sciatica, this may include:
- Advice about sitting, lifting and everyday movement
- Appropriate exercises and gradual rehabilitation
- Osteopathic or manual treatment
- IDD Therapy spinal decompression when clinically appropriate
- Treatment of contributing muscular or joint problems
- A gradual return to work, walking, sport or hobbies
- Monitoring changes in pain, sensation and strength
The aim is not simply to reduce pain temporarily. It is to improve function, restore confidence in movement and help you manage your spine more effectively in the future.
The NHS advises people with uncomplicated sciatica to continue normal activities as much as possible and begin gentle movement rather than remaining seated or lying down for long periods. Activity should still be adapted to your symptoms and clinical findings. NHS guidance on sciatica
Know when to seek urgent help
Most sciatica is not an emergency. However, urgent medical assessment is required if you develop:
- Sciatica affecting both legs
- Severe or rapidly worsening weakness in the legs
- New numbness around the genitals, inner thighs or buttocks
- Difficulty starting or controlling urination
- Loss of bladder or bowel control
- A sudden loss of feeling when passing urine or opening your bowels
These symptoms could indicate serious compression of the nerves at the bottom of the spine. Attend A&E or call 999 if they occur.
Helping you understand your diagnosis
At Buxton & Bakewell Osteopathy Clinic, we believe that you should understand your condition rather than simply be given the name of a diagnosis.
We will explain:
- Which structures may be involved
- Why your symptoms travel into a particular part of the leg
- What may be aggravating the nerve
- Whether further investigation may be helpful
- Which treatment options may be appropriate
- What you can do to support your recovery
- Which changes should be reported promptly
A clear understanding of your condition can replace uncertainty with a practical plan. It helps you make informed decisions, recognise meaningful progress and take an active role in your recovery.
