How long does chills associated with breast abscess last?

If treated....: If your abscess is treated appropriately with drainage and antibiotics, the fever and chills should resolve within 48-72 hours. If the fever/chills persists, then contact your surgeon, the abscess may not have been completely drained (can happen with a complex abscess) or you may need a different antibiotic. This may mean the infection has spread beyond the breast.
