Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more likely. So follow these steps for better symptomatic relief. 1. Apply warm water pad on affected areas of chest. 2. Take painkiller and muscle relaxant drugs like ibuprofen and thiocolchicoside. 3. Avoid movements causing pain. Avoid sudden jerky movements of chest. 4. Avoid heavyweight lifting and strenuous exercise. Don t worry, you will be alright with all these in 1-2 days. If not improving then consult doctor and get done ecg to rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
