Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain as you was hit on your temple the formation of bump is due to
soft tissue injury causing inflammation and
hematoma formation due to ruptured blood vessels..
There can also be due to accumulation of inflammatory exudate, cells and damaged muscle fibres and blood vessels..
The "black eye" is due to blood accumulating in the soft tissues around the eye from ruptured blood vessels secondary to trauma and as the blood will disintegrate the blackness will gradually fade..
As of now you can take anti-inflammatory painkillers like
Advil or
Aleve, do cool compresses over the forehead and around the eye..
You can apply an antimicrobial ointment over the grazes for preventing infection.
Hope this information helps..
Thanks and regards.
