Thank you for posting your query.
It is unlikely to get pain and tenderness after two weeks of mild head injury
, and that too on the opposite side. Therefore, the current pain is unrelated to the first event.
The likely causes could be a sinus infection
) or mild muscle tension headache
You could take analgesics such as ibuprofen for pain relief. If symptoms do not resolve in a few days, you may consult your GP.
Wishing you good health,
