LPRD can indirectly make the ears feel blocked, but throat mucus itself usually does not physically enter or plug the middle ear.
Reflux (from LPR) can irritate the nasopharynx (behind the nose) around the Eustachian-tube openings, causing mucosal edema and impaired tube opening. This can produce:
1. Ear fullness or pressure.
2. Popping or crackling.
3. Muffled hearing.
4. Occasionally middle-ear effusion.
The “mucus” sensation is often due to LPR-related throat irritation, thickened secretions, postnasal drip, or frequent throat clearing—not mucus travelling up into the ear.
Important alternatives-
Blocked-ear symptoms are more commonly caused by:
1. Allergic rhinitis or sinusitis.
2. Nasal congestion.
3. Cerumen impaction.
4. Viral upper-respiratory infection.
5. Eustachian-tube dysfunction unrelated to reflux.
6. Otitis media with effusion.
Persistent unilateral fullness, conductive hearing loss, or adult-onset middle-ear effusion warrants nasoendoscopic examination of the nasopharynx and tympanometry/audiometry.
Next Steps
Manage both possible contributors:
1. Avoid meals for about 3 hours before lying down.
2. Reduce personal reflux triggers such as fatty meals, alcohol, caffeine, chocolate, mint, and spicy or acidic foods.
3. Avoid repeated forceful throat clearing; sip water or swallow instead.
4. Treat coexisting nasal allergy or congestion if present.
5. Do not use ear drops for a pressure problem unless wax or otitis externa has been confirmed.
Seek ENT review if symptoms last more than 2–3 weeks, hearing is reduced, there is significant pain or discharge, or symptoms are one-sided.
