Because that's exactly what it feels like.
I have a really sore breast, it feels exactly like when I had mastitis - I feel as if I've got a blocked milk duct or something, it's agony. Also I'mfeeling a bit shivery and feverish like I'm coming down with a cold.
I went to the doctor a couple of months ago and got referred to a specialist who said there's no probability of breast cancer, but this pain tonight is worse than anything I had then and it feels so familiar. He told me to get some starflower oil or something like that, I can't remember now, wrote it down but lost it. Damn.
Should I go and buy a green cabbage?
