Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have symptoms of constant beep in left ear which are pointing towards viral infection , which usually go away after completing its course . Sometimes infection travel from upper respiratory infection to ears through eustachian tube and block the ears . This is the reasons for constant beep sound in ear and their blockage. Need not to worry. I would suggest you to consult ENT specialist for proper examination. Doctor may order throat swab test , and blood test , also check ears with otoscope . Doctor may prescribe antiviral drugs along with mucolytic agent and decongestants . For now do warm saline gargles , take steam and give dry hots compresses on ears . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
