I know this was posted a little while ago, but just had to respond. Oh my goodness, I came on here looking for this exact same advice! I'm 20+5 and I've started having sharp, stabbing pains in my right breast only, it started a couple of weeks ago and I figured it is my milk coming in but I'm not sure. Did this ever go away for you/did you figure out what it was?
Mine is my right side. It always is. Lanolin oil really helps, coconut oil too. I used to get sore boobs a lot while breastfeeding too. It's so annoying cause it catches in my bra all damn day 😑
