Mastitis is fairly common while nursing, especially in the early days after delivery. The symptoms are a red, tender lump in the breast, a flu-like general achiness, and a fever. If you have any of these symptoms, please call our nurse right away. She will provide instructions for treatment, and an oral antibiotic can be called in to the pharmacy for you. You should continue to nurse while on the antibiotic and you will be feeling much better soon. If there is no improvement in 48 hours on the antibiotic, please call our office.
