gave birth 3 months ago, 1 month ago I had blocked milk ducts and it was cured, in the past few days there have been pus-filled spots on my nipples that have burst, now my whole breast hurts, it is burning inside my breast even though I am not engorged. Doctor, can you tell me if the nipples have pus-filled spots, burst causing pain after treatment for blocked milk ducts, is it a sign of what disease? Thank you doctor.

just gave birth 7 days ago, and for the past 3 days, my breasts have been itchy, I'm afraid there is a tumor in my breast. So doctor, can you tell me if my breasts are itchy after giving birth, is it okay? What should I do, doctor?
