Mastitis. Mastitis is infection of the breast. You should seek medical attention and antibiotic treatment if confirmed.
Big??? Well i'll tell you. Big? Ultrasound is the best way to see if it a cyst or solid. Women with fibrocystic changes may also have a discharge. So check with your primary care doc or gynecologist . Ultrasound can answer a lot of questions.
