I've been hand pumping about 3 times a day, I am mixed feeding mainly formula but like to get a bottle of breast milk a day either to give to baby or freeze. I only pumped once yesterday and when I was giving a bottle in the early hours pumped again then and got about 6 ounces off both boobs. This morning my left boob is so painful and feels really full, but I also have aches like muscular flu aches, if I pump will this feeling go away ? Really feel crap just wondering if engorgement can cause this feeling
