Your symptoms may be due to a viral cold along with allergy-related throat irritation. Allergies can cause post-nasal drip, in which mucus runs down the throat, leading to a sore throat, irritation, coughing, and frequent throat clearing. Dust, smoke, weather changes, or pollen may worsen these symptoms. Antihistamine medicines such as cetirizine, levocetirizine, loratadine, or fexofenadine are often used to reduce allergy symptoms such as sneezing, a runny nose, and throat irritation. Warm saltwater gargles can help soothe throat pain, while steam inhalation can reduce nasal congestion and improve breathing. Drinking warm fluids, such as herbal teas and soup, can also provide relief. If you have a fever or body pain, paracetamol may help when taken in the recommended dose. Try to avoid cold drinks, smoking, and dusty environments, as these can worsen irritation and coughing. Most mild viral colds improve within a few days with rest and fluids. However, if you develop a high fever, pus on the tonsils, difficulty breathing, severe throat pain, or if your symptoms last more than 1 to 2 weeks, you should consult a doctor for a proper examination and treatment.
