Its normal your breasts are getting ready for milk.. warm up wash cloths in the dryer and put them in your bra.. i have to do that every now and then.. warm showers and a good maternity bra with support helps too.
I had stabbing pain and it has felt like I am in a never end "purple nurple". My doc said it was hormonal and the milk glands growing.
Soreness yes but stabbing pains no
Nope not that I've ever heard of.. I would reach out to my doc if I was you and see what they say about this..
