I put ice on it and it builds in to this huge bump.

Hi felix, have you had a knock on the nose recently? which could be the cause of this pain.There is a possibility that there could be a fracture.
Do you suffer from sinus problems? that can also cause lots of pain in the nose and surrounding area.

I think the best thing for you to do, is to visit your Doctor,who can have a look, maybe send you for an x-ray,just to be sure there is not a fracture.
