If the swelling had continued to worsen, Louise, I would have suggested a trip to the doctor ASAP; it sounds like you might have had an infection. Since swelling and pain can also be an early sign of a rare form of breast cancer, it's not a symptom you can ignore. However, since you seem better now, it could be this was a short-lived infection, and the itchy nipple is a side effect. Keep your eye on this, though; if the symptoms return, or the itchiness doesn't abate soon (within a week or so), it would be good to see a doctor, OK? Take care - PJH
Thanks your answer has helped alot. I will keep an eye on it.
