I'm breastfeedingmy 6mo son. Have started to wean him but he still feeds regularly.
Yesterday we drove home from a holiday and he was asleep in the car, didn't wake up to ask for a feed until we got home.
Last night I expressed from my left boob and felt a hard lump on the left hand side (near my armpit), bit worried about it but when I fed him in the night he guzzled and the lump went, boob felt nice and soft.
Now I have a lump in same boob, quite big from what I can feel. It is at the front near where the two boobs meet. I've fed him off this side and expressed, massaging frantically. My bath is being resealed so I can't get in an have a soak 
What else can I do? I think it is a blocked duct, really really do not want it to turn into anything bad
