Because silent reflux (LPR) rarely comes with heartburn, its symptoms often get attributed to something else entirely — allergies, a lingering cold, or vocal strain. The most commonly missed signs include a persistent lump-in-throat sensation, frequent throat clearing that isn't tied to a cold, a voice that's hoarse or tired-sounding especially in the morning, a chronic dry cough, a sensation of postnasal drip with no allergy trigger, and difficulty swallowing certain foods. Some people also notice a bitter or sour taste with no clear cause, or worsened symptoms after lying down, talking a lot, or singing. The common thread is that these symptoms tend to be chronic — lasting weeks rather than days — and don't fully resolve with typical cold, allergy, or throat remedies. That pattern, more than any single symptom, is usually what points toward reflux as the underlying cause.
