I had a BA about 2 months ago. I developed a fever (38.5 C - 101 F), chills and back pain a couple of days ago. I have no other symptoms (sore throat, cough etc) One of my breasts however has enlarged and is sore, especially nearby the side boob area. I had a larger implant put on that side. My pectoral muscle seems sore too. Should I worry? Thanks so much for your attention.
