Itchy throat and cough for months

A continuing cough may follow allergic rhinitis, with mucus draining from the nose and irritating the throat. House dust mites or other indoor exposures can keep symptoms active. Reflux can reach the throat and cause cough or throat clearing, sometimes without obvious heartburn. Asthma may present with cough, wheeze, chest tightness, or symptoms triggered by exercise or cold air. Smoking, vaping, workplace dust, and some medicines can also contribute. A common cold usually settles, so symptoms lasting months should not be assumed to be an ongoing cold. The pattern is useful, but it cannot identify the cause without an assessment.

Book an appointment and keep a symptom record: when coughing occurs, what the throat feels like, sleep disruption, nasal symptoms, meals, posture, exercise, pets, dust, smoke, and any wheeze. Bring a list of medicines and supplements. Reduce smoke, vaping, fragrances, and obvious dust exposure while waiting. Avoid repeatedly starting different cough or allergy products without advice, since this can obscure the pattern. A clinician may examine your nose, throat, and chest and decide whether further evaluation is needed.

Get urgent help for difficulty breathing, blue lips, chest pain, coughing blood, faintness, confusion, or rapidly worsening symptoms. Seek prompt review for unexplained weight loss, night sweats, persistent fever, marked wheezing, or difficulty swallowing. Months of symptoms are not automatically an emergency, but they are a reason to arrange planned medical care rather than continuing self-treatment indefinitely.

Ask which causes best fit your timing and triggers, whether asthma or reflux should be considered, whether your medicines could contribute, and what follow-up is needed if the cough continues.
