You banged your head or face on a bridge your chin and upper lip are scratched but you have this big bump or bruise on your forehead is there anyway you can make it smaller?

It's a bruise -- so ice packs will reduce swelling. 10 minutes on, 10 minutes off, being careful not to get the area too cold. While this doesn't sound like trouble, head injuries always warrant an increased degree of caution. Watch out for blurred vision, nausea, blacking out. If any of these happen, or the headache I know you have doesn't go away in a day, head for a doctor. Also, be prepared for a stiff neck tomorrow -- strong chance of whiplash with this type of injury.
