It is normal to have some decreased movement if a hip joint swells after an injury. As the pain and swelling go away, normal movement will generally return.

Decreased movement can also be caused by a more serious problem, such as:

• Damage to muscles, tendons, bones, or nerves from an injury.
• An inflammatory reaction, such as transient or toxic synovitis, following a cold or other upper respiratory infection.
• Juvenile rheumatoid arthritis (JRA), which causes inflamed, swollen joints that are often stiff and painful.
• Infection in or around the hip joint.

Treatment for a hip problem or injury depends on the location, type, and severity of the injury as well as your child's age, general health, and activity level.
