A blocked duct is not something you "just notice". Any mother who has had
one knows that. It is suddenly there, it usually takes up a fair part of
the breast and it hurts--a lot. Antibiotics are not appropriate for a
blocked duct, and normally blocked ducts resolve within about 24-48 hours,
though, sometimes it takes longer. Two weeks is not what blocked ducts are
all about, except really rarely.
