breastfeeding moms

I have a question.
So my baby has been refusing to drink from my left breast lately. But when he does he'll spit it all up and there will be milk chunks. 
But because he refuses to eat from that side, my breast has been engorged and I'm feeling little bumps on it. Could I be clogged?
