blocked milk duct

Heather
I am pretty sure I have a blocked milk duct or multiple blocked milk ducts. The right side of my right breast is extremely hard and I have intense pain radiating from my armpit. I have tried massaging it aggressively (which kills), I've been putting warm compresses, trying to nurse more frequently, hot shower, and even tried to pump 3 times.  I have not mastered the breast pump (I actually hate it because I feel like I'm doing something wrong) and I've only managed to get a quarter of an ounce, maybe half ounce each time.  I am desperate to fix this so it doesn't turn to mastitis. I start to feel pains in the beginning when she nurses. Anyone have any tips?! The inside and underneath part of the breast is soft so I don't think this is engorgement.
