Thank you for the information,
There are some common causes of such ear pain.The common ones are mastoiditis, middle ear infection, petrositis, sinusitis, etc.
The associated chest pain with nausea and dizziness may be due to the chest infection and should be ruled out.
Since you are having these symptoms for the past few weeks so you should have the relevant investigations done like chest x-ray, ct scan brain, blood counts, etc. after consulting your doctor to know the associated abnormality.
The treatment depends on the underlying cause.The analgesics like motrin, advil, tylenol may help in controlling the pain and inflammation.The antibiotics may be needs to control the associated bacterial infection if any.The other causes should also be ruled out.
Let me know if you have any doubt.
