During pregnancy, completely normal. I always massage my boobs and use cold packs on my nipples. It's a pain, but you can do it :-)
Completely normal. Lots of ladies myself included has very vainy boobs. Its will all the stretching and growing they are taking on get ready for your milk coming in. I have a wheat bag I put in the microwave for a couple of minutes and this helps ease the pain. Dont ware underwire bras. Nice soft supportive bras are best.
