Thanks for your question on Healthcare Magic. I can understand your concern. No need to worry much for your chest pain. In my opinion, you are mostly having pleuritic pain due to previous blunt chest trauma. But better to get done chest x ray at present to rule out internal lung pathology. If chest x ray is normal then no need to worry for major illness. Any warm water pad on affected areas. Avoid movements causing pain. Take painkiller like ibuprofen. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. 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.
