Bumped My Head

I fell off my bike and hit my head on the road. I got a goose egg on my forehead. I hit just above the right temple in the hairline. It happened about 8p on a Sunday. Tuesday morning, I woke up and my eye lid was barely swollen but turning purple. I put ice on it. By 6 that evening, it started to get purple under the eye. The rest of my eye lid was purple by then. It didn't swell under my eye, only a very thin line of color.
When I woke up on Wednesday, my lid and under my eye was swollen and getting really purple.

WHY would I get a black eye from this bump on my head? I bumped it well above my eye. WHY did it take 36 hours to turn purple? My eye was fine all night Sunday and all day Monday. I should mention that I had a cold coming on all weekend. When I woke Monday morning, I was very sick. I was coughing all day Monday. My sinuses were plugged by the end of the day. I had begun blowing my nose. Is it possible the sneezing and coughing contributed? But still? That doesn't make sense. I didn't hit my eye.

Hi
Welcome to the forum!
Even if you have hit your forehead high up the eye can turn black because below the skin there is a common space extending from your forehead to your cheek. Hence if you have a bump on your forehead, the water, blood and chemicals and cells that collect as a result move to lower areas like your eyelids, cheek etc. The color changes that occur are also normal. The redness turns to reddish blue tinge and then yellowish depending on the stage of healing. It took about 36 hours for the eye to turn black or purple because this is the time it took for the contusion to form on the forehead and then the chemicals to seep down.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
