Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.
It sounds like you have had a rebleed under the skin on your forehead that caused the new bump to form.
If you are not having any other symptoms, systemic problems etc I think you will be OK
Of course, the best way to be sure is to have a complete exam by an MD with, possibly,imaging studies.
That being said, from what you have posted I don't really think you need too....
You can always tell your friends how bad the other person looks and claim you won :)
Does this make sense to you?
The bruise may take 3 or 4 weeks to go away.....
The bump may take over a month...the bruises as discussed while our posts crossed each other inside the internet ;)
Does this answer your questions?
I guess you have stepped away from your computer......
