Mastitis
What were your symptoms? Was your boob unbearably sore or did it just feel engorged? Mine's the latter but I'm also running a fever, body aches and chills.
Ugh ? it was like hell for me, I only had it once. It felt like the flu, but condensed down into 24 hours. I took Motrin and rested, applied a warm compress on and off, fed the baby on demand and just tried not to feel awful. My mom happened to be visiting so she helped me a ton with the baby. I didn't call my dr because it got gradually better over 12 hours (and was gone in another 12 except for exhaustion). If you feel your temp increasing anymore than I would call. God bless ya momma!
It's certainly sore but not that sore.
