engorgement ?

meljp430

my lo is 3 days old and i began to feel engorged this evening. he has no distinct patterns and has nursed on both sides a handful of times and now lately has been feeding only on one side. my question is, can i pump (a couple of min.) on the opposite side if he will not feed again for 2 hours? i am lumpy and becoming more uncomfortable, but i don't want to screw it up and make it worse. just looking for some relief.
