A small amount of natural sunlight (5 to 10 minutes a day for several days) may be beneficial in resolving some situations with significant itching.
Talk with your doctor about any severe itching; some prescription medications may be helpful.
Call the doctor if your child has any of the following:
Rash that worsens or becomes painful

What are the long-term concerns?
After healing, your child’s skin may appear darker or lighter in the affected areas. This color change will fade over time.
