Hip pain or sciatica? How to tell the difference

Why symptoms overlap

Pain is not always felt at its source.

A hip problem can refer pain into the thigh or knee, while irritation of a nerve root in the lower back may be experienced around the buttock, outer hip or leg. The hip, lower back and pelvis also share movement demands, so a limitation in one area can change how another area is loaded.

Some people have clinically relevant changes affecting both the hip and lower back. This overlap is sometimes described as hip–spine syndrome. A review of the subject emphasises that overlapping groin, buttock, thigh and knee symptoms can delay the correct diagnosis without a careful history and examination. Read the clinical review.

Hip-related symptoms

What does hip-joint pain commonly feel like?

Pain arising from the hip joint is frequently felt in the groin or front of the thigh. It may also spread into the buttock or towards the knee. Common clues include stiffness after rest, reduced hip movement and pain during weight-bearing activity.

• 01
  Everyday movement

  Walking, climbing stairs, standing, turning or rising from a low chair may become uncomfortable.

• 02
  Hip rotation

  Putting on socks or shoes, getting into a car and pivoting on the affected leg may reproduce groin or thigh pain.

• 03
  Stiffness

  The hip may feel restricted after rest, with a gradual reduction in walking distance or comfortable range.

In adults aged 45 or over, activity-related joint pain combined with morning stiffness lasting no more than 30 minutes can support a clinical diagnosis of osteoarthritis. NICE advises that routine imaging is not usually required when the presentation is typical. Read the NICE guidance.

What about pain on the outside of the hip?

Outer-hip pain may be associated with the gluteal tendons and surrounding tissues—often called greater trochanteric pain syndrome. It may be tender to touch and aggravated by lying on that side, prolonged walking, hills, stairs or standing mainly on one leg.

Although this presentation is frequently called “bursitis”, the bursa is not necessarily the main cause. Gluteal tendon sensitivity and the way the hip is being loaded may be more relevant.

Nerve-related leg pain

What does sciatica commonly feel like?

Sciatica describes nerve-related pain associated with irritation or compression of a nerve root in the lower back. It commonly affects the buttock and the back or side of one leg, sometimes extending into the foot or toes.

• 01
  Travelling leg pain

  Pain may feel sharp, burning, electric or shooting and can extend below the knee.

• 02
  Altered nerve function

  Tingling, pins and needles, numbness or weakness may accompany the pain.

• 03
  Symptom triggers

  Back movement, prolonged positions, coughing or sneezing may alter the leg symptoms.

The NHS notes that lower-back pain may be present but is often less troublesome than the leg symptoms. Read the NHS sciatica guidance. Not every pain travelling into the leg is sciatica: muscles, joints and other structures in the back or hip can produce referred pain without nerve-root irritation.

A practical comparison

Features that may help distinguish hip pain from sciatica

These features provide useful clues, but none should be used as a stand-alone diagnostic test.

Clinical assessment

There is no single test that gives the answer in every case.

Assessment normally combines the history, symptom behaviour and several examination findings. One uncomfortable nerve-movement test or one stiff hip movement does not confirm a diagnosis on its own.

An assessment may include:

• Mapping the location and spread of pain or altered sensation
• Reviewing how the symptoms began and have changed
• Checking walking, balance, hip movement and strength
• Assessing lower-back movement
• Testing leg strength, sensation and reflexes where appropriate
• Using nerve-movement tests when clinically relevant
• Reviewing work, exercise and aggravating activities
• Screening for urgent medical features

A detailed musculoskeletal assessment in Hull can help identify which findings are likely to be relevant and which may simply be incidental.

Imaging decisions

Do you need an X-ray, ultrasound or MRI scan?

Not necessarily. Many hip and sciatic presentations can be assessed clinically, and age-related findings on a scan do not always explain the severity or location of symptoms.

Imaging for hip pain

An X-ray may be considered when the diagnosis remains uncertain, symptoms are atypical or the result would change treatment. Ultrasound can assess accessible tendons, bursae and other soft tissues around the hip, but it cannot assess lumbar nerve roots and does not show all deeper structures within the hip joint.

Learn when a hip ultrasound scan in Hull may be clinically appropriate.

Imaging for sciatica

NICE advises against routine imaging for lower-back pain or sciatica in a non-specialist setting. MRI may be considered when a serious condition is suspected, weakness is significant or progressing, symptoms remain severely limiting despite appropriate care, or a specialist procedure is being considered and the result is likely to change management. Read the NICE recommendations.

Diagnosis-led care

Treatment should reflect the main source of limitation.

For hip-related pain

Management may combine a clear explanation, temporary adjustment of aggravating activity, gradual hip and lower-limb strengthening, movement exercises, walking or stair progression, and a graded return to work or exercise. Therapeutic exercise is a core treatment for hip osteoarthritis, with weight-management support considered where relevant and wanted.

For sciatica

Many cases improve without surgery, although recovery can take several weeks or months. Management may include remaining active within a tolerable level, avoiding prolonged bed rest, changing position regularly, a gradual walking programme and exercises selected according to the symptom response.

Manual therapy may help selected patients, but NICE recommends using it only as part of a treatment package that includes exercise. Specialist assessment may be needed when symptoms remain severe or neurological function is worsening. Learn about sciatica treatment in Hull.

When both areas contribute

Treatment does not necessarily have to address everything at once. Rehabilitation can prioritise whichever problem is having the greatest effect on walking, sleep, strength or everyday activity while monitoring the other area. Progress is best judged through meaningful changes in function—not solely by whether every sensation has disappeared.

Safety

When should you seek urgent medical help?

Emergency symptoms associated with the back and legs

Call 999 or attend A&E if back or leg symptoms are accompanied by:

• Sciatica affecting both legs
• Severe or worsening weakness or numbness in both legs
• Numbness around the genitals, anus or buttocks
• Difficulty starting urination
• Inability to control or feel the flow of urine
• Loss of bowel control or reduced awareness of needing to open the bowels

These symptoms require immediate assessment for possible cauda equina syndrome.

Urgent hip symptoms

Seek urgent help if:

• The hip becomes hot, markedly swollen or discoloured
• Hip pain occurs with a fever or feeling generally unwell
• Severe hip pain begins suddenly without an injury
• You cannot walk or bear weight after a fall or injury
• There is deformity or substantial swelling after an injury

The NHS hip-pain guidance explains when to contact NHS 111 or attend A&E. Progressively worsening weakness, a new foot drop, unexplained weight loss, persistent night pain or symptoms associated with a history of cancer also require prompt clinical assessment.
