Hit my forehead 5 days ago with car door, now eyelid, corner of eye is bruised. It hurts to blink and lump on forehead is sure. Use cold or heat?

Bump on head. Both warm for 29 mins. Cold for 20 mins then off for 20. Repeat till it goes away. You might want to get an imaging study. Ct. To rule out a fracture. Are there any step offs or irregularities around the eye on the affected side. If so your chance of fracture is higher. Good luck. And feel better.
