What would cause ringing in the ears and nasal drip

Hello Anon

Thank you for writing!

Ringing in the ears can be Tinnitus. Tinnitus is the perception of abnormal ear or head noises. Tinnitus is unpleasant enough itself, and is sometimes a symptom of other problems, including hearing loss , tumors, and narrowing of the blood vessels. Noises may be high pitched and “ringing,” or sound more like a clicking. Some tinnitus is pulsatile, which means it may be caused by the flow of blood that accompanies each heart beat, and this happens in cases of narrowing of the blood vessels.

Many diseases and conditions are associated with tinnitus, including:

Hearing loss, the most frequent cause of persistent tinnitus
Exposure to loud noises
Stroke
Certain medications (see below)
Wax or a foreign body in the ear canal
Allergies
Ear infection
Fluid in the ear
Ruptured membrane in the ear
Meniere's disease
High or low blood pressure
Injury to the head or neck
Tumors
Blood vessel disorders, such as an aneurysm or hardening of the arteries
Diabetes
Thyroid problems

Anon, the ears, nose and throat are all connected. Your post-nasal drip may be a connection to your ear problems. Make an appointment with your doctor to know more.
Best,
