Treatment often includes limiting activity to make the child more comfortable. But, there is no danger with normal activities. The health care provider may prescribe nonsteroidal anti-inflammatory medicines (NSAIDS) to reduce pain.
The hip pain goes away within 7 to 10 days.
Toxic synovitis goes away on its own. There are no expected long-term complications.
When to Contact a Medical Professional
Call for an appointment with your child's provider if:
Your child has unexplained hip pain or a limp, with or without a fever
Your child has been diagnosed with toxic synovitis and the hip pain lasts for longer than 10 days, the pain gets worse, or a high fever develops
