Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
The pain and swelling can very well be just due to hard blunt trauma
to the bones.
You can try simple pain killers like paracetamol
or NSAIDs at home and rest.
Less likely there could be a fracture
Watch for increasing swelling, clear fluid coming out of the ear, severe pain
despite pain killers, headache, bleed etc.
If any of these occurs, see your doctor.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
