a question for breastfeeding moms


I have tried Googling this I have tried looking at books I have tried talking to my doctor I can't get any straight answers but does anyone out there know why you get this painful tingling pins and needles sensation in your nipples and then 5 minutes later your baby wakes up wanting to breastfeed does anyone know what that is no engorgement so I don't know is it normal that other breastfeeding mothers experience that
