What to do while dealing with runners knee

Basically, I took on too many miles too quick. And boom knee pain even when walking now. I don't want to stop moving entirely, but I'm just not sure what I should be during this downtime. I'm pretty new to running so only been doing it for about 2 weeks and I'm a little heavier, so it probably beat my legs up. But I love running and don't want to give it up.
