What should you know about persistent postnasal drip?

You may feel mucus at the back of the throat, need to clear it, swallow often, sound hoarse, or develop a cough. Allergic Rhinitis can cause clear drainage and sneezing. Chronic Sinusitis or Sinusitis may add blocked nose, facial pressure, reduced smell, or thicker discharge. Acid Reflux can create a lump sensation, throat irritation, or hoarseness even when heartburn is absent. Persistent drainage and cough can overlap, so Chronic Cough may be considered when coughing becomes the main problem.

Symptoms can be affected by seasons, dust, smoke, fragrances, meals, lying down, or dry air. The appearance of mucus does not identify its cause by itself.

Avoid smoke and other known irritants, drink fluids, and consider a saline spray or rinse used according to product directions with safe water. Wash bedding regularly if dust is a trigger. Note whether symptoms follow meals, sleep, outdoor exposure, or a particular room. A pharmacist or GP can help choose an allergy or nasal treatment and check whether reflux is contributing. Do not use medicated nasal decongestant sprays beyond the stated instructions.

Arrange a medical review when drainage continues despite sensible measures, repeatedly disrupts sleep, affects breathing, or comes with facial pain, reduced smell, recurrent nosebleeds, fever, or worsening cough. Seek urgent help for severe breathing difficulty, swelling around the eye, confusion, a severe headache with a stiff neck, or coughing blood. Prompt assessment is sensible when symptoms are one-sided, follow an injury, or are accompanied by unexplained weight loss.

Does the pattern suggest allergy, sinus inflammation, reflux, or another cause? Would a nasal examination or allergy review help? Which rinse or spray is safe for me? How should I respond if fever, facial swelling, or breathing trouble develops?
