"Ugh, has anyone ever had something like this where their chest feels sore? Since morning my right breast is unbearably painful, I've squeezed everything out, it still hurts and there's swelling, my temperature went up to 37.3. What did you do to relieve yourself? My daughter is breastfeeding! I can only go to the hospital tomorrow."
