Painful stinging sensation

[Olive]

holly if you were on AB's last week then you may well have thrush as the AB's kill the bad and good bacteria, im using nilstat too

As AJP says, the fact that you have been on ABs makes thrush a likely explanation. But the white nipple could be vasospasm as well. Seeing an LC could be a good idea and the ABA helpline also should be able to help you figure out what the cause is. The good news is that all these things can be treated so it will get better!

I posted before I got to see your reply, Holly. It's really frustrating, and I'm sorry that your experiencing these problems, hun. BF is very natural, but it doesn't mean it comes easy, or that it's at all instinctive. Hang in there, you're doing really well to make the effort to work out what is happening, especially when you've been struggling with mastitis already.

If the white coating on your bub's tongue is not there anymore then it definitely will have been milk. With your nipple looking whitish straight after a feed (and especially if that goes away later too) that could be a sign of issues with your baby's latch and that your nipple is being compressed in bub's mouth the wrong way, affecting the blood flow, and causing the stinging. Does it hurt particularly badly when you feed him? Especially when he first gets attached? Does the white look to your nipple go away after some time? Is your nipple shape round or squeezed into a different shape when DS finishes feeding?

Your areola shrivelling sounds like it could be a vasospasm related thing?

Can you call the ABA helpline to ask for advice?
