Thank you for posting your query.
Based on the description, your son has suffered from mild head injury
and scalp hematoma
(bleeding under the skin over head).
He should recover well on its own within another 2-3 weeks. Blood in the eye would also go.
Pea size bumps are possibly small blood clots
. No need to worry about them. If it is painful, analgesics such as ibuprofen
may be used.
