My daughter is 8mo & im breastfeeding. The last few days my breasts have been really itchy.. & today I've just noticed what looks like a blister on my right breast? (Use this one most for feeding) it's not near the nipple so not latch related & we have no problems feeding. My daughter does like to grab/stretch (lol)/scratch them when she's feeding so I have some scratches do you think it's related? It's not painful or leaking. Just a bit worried I shouldn't ignore it... TIA.
