Hi,thank you for posting your query on health care magic.
I have gone through your query.
Pain and ringing in the ear(tinnitus) might occur due to
blunt trauma.
If your wife suffered from bleeding in the ear,reduced hearing,giddiness,
loss of consciousness,vomiting,
facial paralysis,etc,then only it needs to be a concern and in that case CT scan
temporal bone might be needed to rule out internal injury.
Ear pain and tinnitus should resolve in few days most probably.
At present,she may get relief by taking
Analgesic with Antiinflammatory like Ibuprofen.
Avoid loud sounds.
Still it would be advisable to consult an Otolaryngologist doctor for the ear examination.
Hope this answers your question.Take care.
