itchy Breasts?

I've been exclusively pumping for about a week now due to breastfeeding complications but starting yesterday I have had itchy breasts. It's not the nipple area and I don't feel any pain (yet) anywhere just really itchy. Has anyone experienced this? I can't figure out if it's a yeast infection or if it's just itchy because I don't feel pain only discomfort from the itching. Any advice will help, thanks Mommas!!
