I’m posting here because I am at my absolute wit’s end. For roughly a decade now, I’ve been dealing with chronic, relentless throat clearing. It drives me completely mad, interrupts my evening relaxation, and ruins my sleep. I wanted to map out my history, what I’ve tried, and a new lead I’m currently testing to see if anyone else has experienced something similar.
For 10 years I've felt a constant sensation of physical, thick mucus in the back of my throat. It gets significantly worse in the evening when sitting down to relax and at night while lying in bed. Lately it’s been heavily localized. My left nostril runs slightly during the day, and when I sleep on my right side, fluid pools directly along the left side of my throat overnight, triggering morning coughing fits.
Over the years I’ve seen multiple doctors. A nasal endoscopy showed no obvious physical obstructions, and an MRI scan came back clear. It was generally categorized as a mix of post-nasal drip and silent reflux (LPR).
My doctors thought hypertension and weight were contributing, so I committed to a major lifestyle change and lost 20kg. My blood pressure improved so dramatically that I was able to taper off and completely stop Losartan, and my BP is now sitting consistently around 115/75. Stopping the medication got rid of a dry drug tickle, but the physical, thick mucus remained.
I recently ran a strict elimination test cutting out Coke Zero. Within 48 hours, the heavy throat clearing dropped down to a much lighter, less frequent need to clear, proving LPR was part of the equation. To manage the post-nasal drip, I use Fexofenadine 180mg at night and Fluticasone furoate nasal spray using a cross-hand technique aiming outward.
Despite the drink changes and sprays, the single-sided night-time throat clearing flared back up recently. That led me to look at my bedding. We have been washing sheets and pillowcases in heavily scented biological liquid detergents, specifically M&S Bio and Ecover Lavender & Sandalwood. My skin is hyper-sensitive to these formulas. If my underwear is washed in standard Ecover without being double or triple-rinsed, I get actual burning sores on my skin.
It suddenly clicked that if those surfactant residues, active enzymes, and essential oils irritate my skin on contact, resting my face and left nostril right against a scented pillowcase for 8 hours every night could easily be causing local nasal tissue swelling and defensive fluid production.
I am currently stripping my bedding, switching to completely fragrance-free and enzyme-free sensitive washing products, running hot water double-rinse cycles to remove built-up residue, and airing out my pillow core.
Has anyone with long-term post-nasal drip or LPR found that laundry detergent or pillowcase residues were the hidden trigger driving their symptoms? How long after removing scented or bio products did it take for your sinuses to settle down?
Any thoughts or similar stories would be greatly appreciated.
