Painful Lump

Kat
I think I have a clogged duct on my left breast. I thought I was just engorged so tried feeding my son on it to relieve it but it didn't help one spot so I pumped for 20 mins, got 3 oz from it, it still hurts. Tried massaging it when he ate from it again, still nothing. It's been a few hours and it really hurts, any suggestions?
