you have already suffered due to delay in treatment for your dental infection, so it would be unwise to self medicate at home. The best course of action would be to visit ur local ENT specialist
.If it is wax then appropriate topical medication
will soften it and make wax removal absolutely painless.However without consultation self cleaning efforts may cause otitis externa
(external ear infection
) and become painful. Donot delay and visit your doctor soon.
Hope you feel better soon
