Large lump in left breast...

Dani

Last night while I was breastfeeding my son I noticed a large lump on the top of my breast (inside).

It seemed to go down with nursing, but never went away.

I tried a warm shower and massaging the area with no luck!

I pumped while massaging and still no luck!

Is this a blocked duct? I don’t want it to lead to mastitis.

What else can I do to relieve the pain? It’s not too painful yet, but it’s noticeable especially when my husband hugs me! :(
