For cellulitis/mastitis of the breast. When I got sick, I didn't know why or what for. I had chills and a fever. My husband called my daughter to come over to check up on me. My daughter took my temp and it was over 102 degrees. I felt like crap. I thought I had the flu. My daughter MADE me go to the ER. When I got there, my temp was over 103. They checked me from head to toe but nothing showed up. They decided to keep me overnight for observation. The next day when I woke up, my breast was red and had swollen about two sizes larger than the other. It was hard as a rock and very painful. My temp stayed in the 100's for that day. It didn't break until the following day.
I had went into the ER on Monday night and I didn't get released from the hospital until Friday afternoon; and that was because I begged the doctor to let me go home. During the stay, I was on round the clock IV fluids and IV antibiotics. The antibiotics that I received were Vancomycin and Clindamycin. I will have to take the Clindamycin orally for another week.
Anyway, that where I was.
P.S. Yes, it's unusual for a postmenopausal woman to get this. Hopefully, that's all it is!
