Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more. But better to first rule out lung infection (pneumonia) because pneumonia can cause cough and pleuritic pain (chest pain one coughing). So consult pulmonologist and get done clinical examination of respiratory system and chest x ray. If these are normal then no need to worry for pneumonia. Musculoskeletal pain is more likely in your case. So follow these steps for better symptomatic relief. 1. Avoid movements causing pain. 2. Avoid heavyweight lifting and strenuous exercise. 3. Avoid bad postures in sleep. 4. Take painkiller like ibuprofen. Also take antihistamine like levocetrizine for cough. 5. Apply warm water pad on affected areas. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
