There is a connecting tract (known as Eustachian tube) between the nasopharynx
& middle ear through which infection can spread to ear.
Also obstruction to this Eustachian tube (most commonly due to cold/upper respiratory tract
infection) can lead to ear pain
by un-equalisation of pressure between the nasopharynx & middle ear.
Hearing is also reduced due to this.
The management consists of:
1. Drinking of warm fluids to reduce throat pain
2. Antihistamines to provide symptomatic relief.
3. Nasal decongestants to relieve ET tube obstruction.
4. Analgesics to take care of pain & fever(if any)
So...it will be better to consult an ENT specialist
& start treatment.
Wishing you a speedy recovery.
Thanks & take care.
