I would know if I had mastitis, right?

I had mastitis with my first kid. Woke up with a hard lump/clog and within an hour had chills, aches, and a fever.

I was driving today and suddenly felt so tired and cold. Got home and had chills and aches, and now I have a fever. No other symptoms. One of my boobs is achier than the other but the rest of my body aches, too. If it were mastitis, I would feel pain in my boob, right? I’m so damn sleep deprived right now, I wouldn’t be surprised if I woke up fine tomorrow if I can get a few hours in.
