I have something on my right breast, if you press with your hand it's soft, there's nothing, but if you feel it with your fingers, carefully looking like an education or maybe it's a milk gland or a knot, I don't know, in short, right where the armpit ends and starts the chest. If you feel it with your fingers, deep down, it feels like something is there, I thought it was a stone (breastfeeding), not it Maybe this is normal? You can feel it only when you're looking for it with your fingers But when you hold the breast generally in your hand, there's nothing.
