The Jersey Shore star, 31, shared on her Instagram Story that she “felt the onset of mastitis starting” three weeks after giving birth to her third child, son Angelo James. “Had the worst chills and fever the other night & I’ve been pumping and feeding my boobs off all day,” Polizzi wrote on top of a selfie featuring the new mom looking sleepy. “Jesus take the wheel.” Mayo Clinic defines mastitis — which often results from a build-up of milk in the breast duct — as “an inflammation of breast tissue that sometimes involves an infection.” “The inflammation results in breast pain, swelling, warmth and redness. You might also have fever and chills,” the organization notes. Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?

The reality star flaunted her post-baby figure on Instagram in a bikini two weeks after giving birth, all while still keeping it real about postpartum. While advertising that her bikini was part of The Snooki Shop, she also told fans, “If you zoom in I’m still wearing my diaper.” Polizzi has been open about her postpartum struggles, previously sharing an image of her diaper routine while joking that she would include it in the next line at The Snooki Shop.

But I’m allowed to look on the bright side of things and want to get back into shape. Don’t punish me for that.”
