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!
