I'm having problems with on of my boobs.. She started crying one started to over flow.. Well both.. But just one is in pain and I cant give her that one cause I tried and it hurt so bad I pulled my boob away from her in like a second from the pain. The other is fine.. But I can't handle this pain tho.. Is there anything I can use or take for pain relief
