I would go and see a LC about vasospasm. It isn't just from poor attachment, it can be a secondary thing from microtrauma to nipple (after thrush etc). It is extremely extremely painful (it is a bit like chillblains of the nipples), you have to keep your chest warm (heat packs on nipples, and you can get these breast warmers for between feeds). I had to ake huge doses of Blackmores Biomagnesium to clear it up.
