Hello dear,
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, secondary to an upper
respiratory tract infection,
sinusitis, cold & congestion, can lead to locking/ pain in ear by causing un-equalisation of pressure between the nasopharynx & middle ear.
Management includes:
1. Antihistamine preparations like Allegra.
2. Decongestant nasal drops.
3. Antibiotics based on culture & sensitivity reports.
4.
Analgesic like
Paracetamol.
5. Steam inhalation and warm salt water gargle.
6. Maintenance of adequate hydration & nutrition status of the body.
7. Protection from cold, dust & other allergens.
Wish you good health & a speedy recovery.
Take care.
