How can i tell if i have block ducts? Can a low supply mom have block ducts? I have a very painful lump at my areola, can anyone advise what can i do? Pumping hurts a lot now. How do i treat milk blister?

Yes, Low supply can have block ducts too! Get a hot compress and roll it over your breast, massage on the block area and pump it immediately. It takes a few tries for it to be fully unblocked. For milk blister, use a sterlized needle and poke it.
