I don't really have a too large milk supply but just an "overactive letdown response". Painful, fast, forceful letdown of milk. If I want to see a doctor about this to have my hormones tested, to be sure that hormonal problems aren't the cause, what kind of doctor is best to see? I don't have a doctor right now except my OBGYN from 8 months ago... Sometimes rarely pituitary problems can be the cause of this and not too many aveoli and I want to be sure.
