Single milk duct engorged?

Hey guys!

I'm pregnant with #2 and have weaned Fin for a couple weeks now and the other day I started having pain in my left breast and it's like only one milk duct is engorged?! It's that normal? It doesn't seem clogged because when I massage it, it does leak. I've never had mastitis but I don't think this is it, is it?
