creaking scary noise.

I get a very annoying creaking sound whenever i go slow it almost sounds like the tires are rubbing but i go perfectly stright when not holding the wheel and i also cannot tell what side of the car it is coming from, this starting about a week after i hit a curb if that could be it but it seems like that would be a very delayed reaction. like i said after i get past about 15-20 miles an hour i can not hear this sound anymore, can anyone shed some light on this subject?

Sounds like wheel bearings. Try jacking the car up and trying to rotate each wheel by hand. The front ones should be hard to turn, but shouldn't feel 'crunchy' as if there's something broken in them when they spin.

If it is not the bearing you should check your brakes and hubs.
