Take a warm shower and hand express. Not sure if you don't want to hand express either.

Go to kellymoms.com and look up the engorgement and reverse pressure article. My lactation consultant had me do this and it helped tremendously. It does take a little while before a feeding though so make sure you give yourself time before your baby gets too fussy. 

I take a shower and hand express enough to be comfortable. Apparently supply isn't an issue that I'm having. I am so afraid to pump!
