Hi Dear ,
Welcome to HCM.
Understanding your concern. As per your query you have symptoms of popping in ears upon blowing the nose and sneezing. Well there can be many reasons for symptoms you mention in query like allergies ,
hay fever , nasal polyps , chemical exposures ,
chronic sinusitis , tumors and a deviated septum. In some cases mucus spread from upper
respiratory tract infection to ears through eustachian tube and cause popping in ears. Need not to worry. I would suggest you to
consult ENT specialist for proper examination. Doctor may order CT scan , nasal endoscopy, endoscopic examination and blood tests . Doctor may prescribe antibacterial or antiviral depending upon the diagnosis along with decongestant or expectorant . Doctor may also prescribe anti allergic or recommend surgery in case of deviated
nasal septum or nasal polyp . For now apply warm compress on nose , keep your head elevated while sleeping , take steam , also apply dry warm compresses on external ear and take benadryl twice a day .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
