Quitting breastfeeding cold turkey..day 4 still engorged.

I am on day 4 of quitting breastfeeding cold turkey and am still painfully engorged...I was exclusively pumping and had an oversupply. My OB did recommend going cold turkey btw. Has anyone else been engorged this long? I remember only being in a ton of pain the first 48 hrs with my first...is there an end in sight?
