If your child is limping, it's usually the sign of a minor injury such as a sprain or splinter. However, if there's no obvious cause, see your GP as there may be a serious underlying medical condition.
If your child has started limping, find out if they've injured their leg or foot or stood on something sharp. Inspect the soles of their feet and in between their toes for a wound or blister.
If there's no wound or sign of injury, your child may have an underlying medical condition that needs investigating by your GP. This will usually be done by arranging blood tests and an X-ray of your child's hip.
If your child also has a fever or seems unwell, take them to your GP as soon as possible. They'll need to be seen urgently by a specialist to rule out a bone infection (osteomyelitis).
Some of the possible causes of your child's limp are described below. However, it's important not to diagnose the cause yourself – always leave that to a doctor.
Irritable hip (also known as transient synovitis) is a common childhood condition that causes hip pain and limping. Children with irritable hip may also be reluctant to place weight on the affected hip joint, making it difficult for them to stand or walk.
The condition occurs when the lining that covers the hip joint becomes inflamed, although the cause of inflammation is unclear.
A diagnosis of irritable hip is only made after other more serious causes of a limp are ruled out.

Some viral infections can cause painful joints. If your child has a fever and pain in many joints, as well as a limp, they're likely to have a viral infection.
However, make sure you see your GP for a proper diagnosis as they'll want to rule out more serious bone infections, such as:
Arthritis is often associated with older people, but can sometimes affect children. This is known as juvenile arthritis.
Arthritis causes pain and inflammation (swelling) of the joints and bones. A child with juvenile arthritis will feel stiff, especially first thing in the morning, and won't be able to move their joints freely.
There's no cure for arthritis, but there are treatments that can slow down the condition and help to control the symptoms.

Slipped upper femoral epiphysis (where the growing part of the bone in the hip joint moves) is more common in adolescents. This usually happens gradually over time, and tends to affect older children, although it can suddenly happen as the result of an injury.
If your child has a slipped upper femoral epiphysis, they should avoid walking or rotating the leg. They'll need to have surgery as soon as possible, to realign the bone and fix it into position.
