I need help 😥

Kima

My right breast has been hurting for the past two days, and when my baby feeds it’s excruciating but Ive been taking it, it’s only getting worse so I’ll be pumping that one till it stop. I tried to see if there’s a tear on my nipple or something but I can’t see anything, I did notice there is a blue vein under my nipple and when I press/squeeze on it ,it hurts. My LO is teething and I am her comfort and it’s sucks that I can’t feed her on the right breast. Also because my right breast fills up really fast 😐 idk why. I just need it to stop hurting. What is going on 😥😭
