My 9 yr old son bumped heads with his brother, he has a goose egg between his eyebrows just above his nose, did the RICE treatment straight away. No signs of concussion, and no bruising on the bump. After a day the bruising developed just under his eyes, a day later it's now on his eyelids (looks like he's wearing eyeshadow). Should I get him checked out, or should I leave it a couple of days before taking him to be checked out? The swelling has gone done. It has been three days.
