Hi welcome to health care magic forum,
Impacted wax or cerumen in right ear may cause problem in putting hearing aid
Wax may get infected or impacted cause external ottitis .
of wax leads to mild to moderate pain or otalgia.
Infection of wax leads to external ottitis . Externa ottitis leads to ear pain
and may lead to inflammation and sore behind the ear (post auricular space).
In my opinion you can put a broad spectrum antibiotic ear drop
for 4 to 5 days and if no relief than see an ENT specialist
for thorough clinical examination and cleaning of the ear followed by a proper otoscopic examination.
