Thank you for posting your query.
Your current symptoms are possibly due to a scalp hematoma
(bleeding underneath the skin over the affected area). This is not a serious condition, and subsides with medical treatment in a few days.
As of now, you could take analgesics such as ibuprofen
tablets for pain relief.
However, if the headache worsens in severity, or if you develop vomiting, blurred vision
, or decreased alertness, then you could consult a doctor in the ER.
Wishing you good health,
