Clogged milk duct

I’m 8 weeks postpartum EBF. Since Friday night I’ve had a hard painful lump on my right boob. It’s becoming extremely painful, keeping me up at night etc. I’ve tried multiple things to try to get it to release:

- hot shower/massaging

- pumping

- ice

- dangling feeding

- dangling over a hot epsom salt bowl

- haakaa filled with hot epsom salt

I don’t know what to do anymore! My baby doesn’t seem satisfied when feeding off that boob. She’ll cry at the breast (I’m assuming because milk flow is weakened). Anyway, what can I do to help this go away? And quickly too?
