Shooting boob pain

It’s 1:30am and I woke up with this shooting pain on my left boob. It’s at the bottom of the boob and the whole thing feels so hard. I’m pumping now to see if it gets better.

I’m 5 months PP and exclusively pumping and breastfeeding. I’ve had clogged ducts before but they were always on the side or top of the boob, never at the bottom like this and it feels different. What could it be?
