When an itchy throat does not go away

Continued exposure to dust, pollen, smoke, fragrance or dry air can keep the throat sensitive. Allergic rhinitis may cause ongoing nasal blockage or mucus draining down the throat. Reflux can irritate the throat, especially after meals or when lying down. A recent infection may leave a cough or scratchy sensation after other symptoms improve. Less common causes need consideration when the pattern is unusual or steadily worsening.

Write down when the itch began, whether it varies indoors or outdoors, and any link with meals, sleep, exercise or voice use. Drink fluids and reduce smoke, vaping, dust and strong scents. Treating nasal symptoms may help when drainage is present; ask a pharmacist or clinician before starting allergy medication, particularly if you take other medicines or have a long-term condition. Avoid repeatedly using products without checking their ingredients.

Call emergency services for sudden throat or tongue swelling, difficulty breathing, faintness or inability to swallow saliva. Seek prompt medical care for a new neck lump, severe pain, coughing blood, chest pain, persistent hoarseness, unexplained weight loss, or symptoms that are rapidly worsening. Otherwise, book a routine appointment for an ongoing symptom so the nose, throat and chest can be assessed.

Could an allergy, irritant, reflux or medicine be maintaining this symptom? Should my nose, throat or chest be examined? Would testing or a treatment trial help? Which changes should bring the appointment forward?
