Thank you for your query.
around the nose can give rise to collection of blood below the skin and around the eyes which is giving rise to red colour of the white areas of the eyes. If the child is sleeping as per schedule then most probably things are fine and nothing needs to be done. However, in case the following symptoms are seen then the child need to be shown to a doctor immediately:
2. Unusual crying
4. Abnormal movements.
This swelling shall take some time to subside though it is going to increase for about 24 hours.
I hope I have responded to your query to your satisfaction.
Wishing your son a speedy recovery.
