Lump in breast

Nav • First time Mommy to little munchkin 💙

I am exclusively breastfeeding from jan 2019 first baby. I have been feeling a lump in my breast for some time ignored it thinking it might be engorgment or clogged duct.

The size of my nipple is also getting small.

But from last week its getting sharp and i feel frequent sharp pain and itching and its red from where its sharp lump. And its towards armpit. M not sure if i shal worry or let it go.
