Dear Customer (name blocked for privacy),
I believe that you are suffering from either a local breast infection (? abscess) or a foreign body reaction to the pierced ring.
You need to be seen by a specialist at the earliest, who would be able to give you either prescription medicines, or drain the pus, as needed.
I do not agree with the piercer's opinion about healing goign on for an year..
