Re: plugged duct maybe?
What you describe does seem to match the symptoms of a plugged duct. Some residual soreness is probably normal, but do your best to keep on emptying that breast, and just generally keep an eye on it. If the plug returns or worsens, or you see any combination of increased pain, red patches or streaks on the exterior of the breast, aches, fever, chills, or general "flu-like" feelings, you probably want to talk to your midwife or doctor about the possibility of this being mastitis.
