Hi Dear , As per your query you have swimmer s ear along with pain and dizziness . Swimmer s ear is an infection in the outer ear canal . Swimmer s ear is also known as acute external otitis or otitis externa. The most common cause of this infection is bacteria invading the skin inside your ear canal . In some ceases like in lower immunity and when it left untreated this infection spread to further and cause further complications like pain and dizziness as happening in your case . I would suggest you to consult ENT specialist again for proper checkup . Doctor may order certain test like CT scan and examine with otoscope . Doctor may prescribe sstronger antibiotics , steroid ear drops , antiemetic drug and sometimes place tubes for drainage . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
