Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Causes of earache are wax granuloma,
otitis externa, acute
otitis media, tumors, mastoiditis. To rule out these causes, an otoscopic examination of ear is needed.
Causes of referred earache involves
dental caries, tongue lesions, tonsillitis,
pharyngitis, lesions in pharynx, base of tongue, temperomandibular joint dysfunction.
To rule out any of these causes, an examination of oral cavity and throat should be performed. If the cause is not detected then go for MRI brain.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Manu Wilfred
