Hello, Your symptoms are pointing towards ear infection leading to pus discharge that is appearing as a yellow colored liquid. At times perforation of the eardrum can cause infection in the ear while infection in the ear can also cause perforation of eardrum due to perforation. You need to take another course of antibiotics like Cepodem, Augmentin etcetera. Along with it, you can also take painkillers if there is a pain in the ear. Use antibiotic ear drops and decongestant nasal spray like Otrivin. In case if the symptoms do not get better, you can be advised manual drainage of ears so that infection heals faster. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
