Shooting pains? Thrush?

Le

I am exclusively pumping and last night I had shooting pains in my right breast all night. They were not super sharp, but definitely there. I do not see any white patches in my daughters mouth and my nipple is not flaky or red. Could this be the beginning of thrush or am I being paranoid? Any other reason for shooting pains? Can I still feed her pumped milk from last night?
