Thrush on your nipple?

Amber
I believe I have thrush on one of my nipples. I exclusively pump so I'm not sure if I can still transfer it to baby that way, but it's become very sore when pumping and for at least an hour afterwards. Also I've noticed a small white spot on my nipple that is extra sensitive. 
Do you ladies have any home treatments for thrush or something over the counter I can get, or do I need to go to a doctor? It's really not too terrible right now, just uncomfortable, but I don't want it spreading or getting worse. Thanks in advance!
