Brief Answer: Attributed to allergic tracheo-bronchitis. Detailed Answer: Dear XXXXXXX Thanks for your query. The symptom as mentioned in your post is attributed to allergic tracheo-bronchitis. The light black mucus in cough is due to presence of dust/ pollution which causes irritation of the respiratory passage & post nasal drip, which is responsible for tingling sensation in throat. The use of rajnigandha & tulsi and alcohol intake has caused reduction in your immunity level, making you prone to inflammation/ infection of respiratory passage. Presenting with such symptoms, I usually treat my patients with: 1. Antihistamine preparations like Allegra 60 mg twice a day for symptomatic relief. 2. Antitussive preparation like Grilinctus syrup 10 ml thrice a day to take care of cough. 3. Avoid smoking, chewing tobacco products & alcohol consumption. 4. Maintain adequate hydration & take a healthy balance diet. 5. Also make sure that you are well protected from cold, dust & other allergens. If symptoms still persist, kindly consult a Pulmonologist & get a proper clinical examination done. Investigations like complete blood count, sputum culture & sensitivity, pulmonary function tests & X ray of chest will be helpful to rule out any pathological cause for symptoms. In Delhi, All India Institute of Medical Science (AIIMS) is the best for treatment. There is no need to worry, you will be fine. Wishing you a good health. Please let me know if I need to clarify further. Take care.
