Thanks for your question on Health Care Magic. I can understand your concern. By your history and description, possibility of lower respiratory tract infection (LRTI - pneumonia) is more. You are having fever with chills, cough, thick expectoration, pleuritic chest pain (pain on coughing and deep breathing). All these are characteristic features of pneumonia. So better to consult pulmonologist and get done clinical examination of respiratory system and Chest x ray. Chest x ray is must for the diagnosis of pneumonia. You will need antibiotics, mucolytic, expectorant drugs. Drink plenty of fluids orally and keep yourself hydrated. Quit smoking if you are having this habit. Don t worry, you will be alright. First diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
