I'm glad you caught it in time and got antibiotics! I'm on the same right now- I've been BFing my DD for 14 months, and I thought I was past that stage. But a few days ago my right boob got really sore- exactly the same as you, no lump, no redness, and within a few hours I felt like I'd been flattened by a truck.
It's funny, because I had mastitis twice when she was less than a month old, and both times I had the big swelling and hot red lumps. Both times I got ultrasound treatment and didn't need antibiotics. I didn't even realise I could still get mastitis at 14 months (sounds like a dumb thing to say, especially since we're heading for weaning, but I just didn't think about it now that my milk supply is right down).
Anyway- from one mastitis-inflicted BFing mum to another, here hoping you feel better really soon. It sucks! I've never felt so tired, ever.
