Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more because your pain is associated with specific movement and position. And these are characteristics of musculoskeletal pain. But you are also having chronic cough (cough for more than 1 month), so we shouldn t also rule out tuberculosis and pneumonia as they can also cause chest pain. So first get done chest x ray. If chest x ray is normal then no need to worry for lung diseases. Take simple antihistamine for cough. For musculoskeletal pain, follow these steps. Avoid movements causing pain. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Take painkiller like ibuprofen. Apply warm water pad on affected areas. Don t worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
