Itchy throat and cough that will not go away

Symptoms can persist when the trigger remains present. Allergic rhinitis may cause continuing nasal drainage, while dust mites, smoke, fragrances, or workplace particles can repeatedly irritate the airway. Reflux may cause cough and throat discomfort after meals or when lying down. Asthma can cause cough with wheeze or chest tightness, sometimes without a dramatic breathlessness episode. A viral illness can leave irritation behind for a while, but a cough that does not improve deserves attention. The symptom is not a diagnosis, and its persistence does not show that one particular condition is responsible.

Write down when symptoms occur and whether they change with meals, lying down, exercise, air-conditioning, dust, pets, smoke, or fragrances. Drink fluids, use warm drinks, and keep the air comfortably humid if it is dry. Avoid smoking and vaping, and reduce known irritants. Follow medicine directions and ask a pharmacist before adding an over-the-counter cough or allergy product, especially if you have other illnesses or take regular medicines. Take your symptom and medicine list to the appointment.

Seek emergency help for severe breathing difficulty, blue lips, swelling of the tongue or throat, faintness, confusion, or inability to swallow saliva. Obtain prompt assessment for chest pain, coughing blood, high fever, dehydration, significant wheezing, unexplained weight loss, or rapidly worsening symptoms. If none of these warning signs is present, arrange a routine appointment because ongoing symptoms may need examination and a tailored plan.

Ask whether your symptoms suggest allergy, reflux, asthma, infection, or an irritant; whether any medicine could be contributing; and what change should prompt earlier review.
