    When to see a doctor

    Make an appointment

    Breast rash is rarely an emergency. But make an appointment with your doctor if your breast rash doesn’t respond to self-care within a week or two, or if it is accompanied by:

    • Fever
    • Severe pain
    • Sores that won’t heal
    • Signs and symptoms that worsen or last longer than a week

    Self-care for breast rash

    In the meantime, you may find some relief from your breast rash with these measures:

    • Take a warm bath or place a warm washcloth over the rash for a few minutes.
    • Apply a fragrance-free moisturizer to the area.
    • Take care of your skin. Don’t scratch the rash.
    • Avoid extra stress, because stress can make a rash itchier or make you more likely to scratch.
    • Think about recent behaviors that may have caused your rash. Have you tried a new soap? Have you been wearing scratchy clothing? Stop using any new products that may have caused your rash.
