Drop any activities except for breastfeeding to lie down and rest. If you are doing all of this and are the same or worse after 24 hours, contact a health care provider. If your fever or pain is worsening rapidly then see your doctor the same day. You may also wish to discuss pain relief options with your health care provider. Many mothers find that pain relievers which have anti-inflammatory effects are the most useful. Antibiotics may be required to treat the infection. Most antibiotics are compatible with breastfeeding.
