When did your milk come in after birth?

I’m 2.5 days pp and omg it is killllling me. I felt something dripping from the other side when I was feeding her and thought it was blood bc my nipples hurt so bad. But it was just milk lol. And the side she was feeding from felt tingly and almost kind of numb after she got off 😮 it’s so crazy feeling. But man does it hurt!! Any remedies for the pain??
