This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Eustachian tube dysfunction is a common cause of ear fullness.
This tube connects the middle ear cavity to the throat.
Inflammation from allergies or dental works can block this tube and prevents air ventilation in the middle ear cavity.
Treatment consists of a steroid nasal spray like Flonase twice daily, a decongestant like Sudafed 120 mg twice daily for 2-3 weeks.
Infection is unlikely since you do not have any fever, swollen glands or any ear drainage.
You should consult with a ENT specialist as well.
It was my pleasure to help you today.
