Clogged leaky nipples! Ouch!

I've been leaking colostrum for about 6 weeks now so I'm used to that. Last night I was leaking from both sides a lot more than usual and I was a little annoyed lol. Well I woke up around 6am because my SO brushed my nipple by accident in his sleep and it hurt like hell causing me to wake up. My right nipple was super sore so I sat up and noticed white discharge all in the crack of my nipple (not areola my actual nipple) I wiped it off carefully and went back to sleep. I'm curious though, colostrum is usually yellow and this was white. Was it something else and that's why my nipple was so sore? Was it clogged? Any information you have would be helpful. Thank you!
