i kept getting blocked ducts (most times bar 1 i managed to unblock using my eletric toothbrush to vibrate the blockage out - a tip given to me by an LC) and it ended up being my bra, it was cutting in along my boob. I was wearing moulded cup ones and ended up having to go with a normal tshirt bra until my milk settled down. Maybe something to consider? Ducts are pretty close to the surface and super easy to **** off!
