Hi welcome to the health care magic The ear pain along with discharge suggestive towards ear infection like that of otitis media... If only impacted wax is the cause than otic carbamide peroxide like ear drops used for wax removal But you have been prescribed antibiotic ear drops and oral antibiotic... Hence you are having acute infection as the cause and with subsidence of infection your pain will be relieved... Consult otorhinolaryngologist for Otoscopy examination if you have not consulted yet... And follow doctors prescription... If edema more in ear than doctor will also put glycerine soaked cotton in ear for one day Take care Hope your concern solved
