Hello dear, The symptoms as mentioned in your post suggest that you might be having Allergic tracheo-bronchitis. Aggravation of symptoms on lying down can be attributed to throat irritation secondary to post nasal drip. Examination of the throat using a laryngoscope and X ray of the chest will be helpful in clinching the diagnosis. Management includes: 1.Antihistamine preparations like Allegra & Cough expectorant syrup for symptomatic relief. 2. Montelukast preparations- used as a maintenance therapy. 3. A course of antibiotics may be taken to prevent secondary bacterial attack. 4. Maintain adequate hydration & healthy balance diet. 5. Steam inhalation. 6. Also make sure that you are well protected from cold, dust & other allergens. So, it will be better to consult an ENT specialist for proper clinical examination & start treatment as advised. Wishing you a good health. Take care.
