[|Human|] Hello, I am a 21 year old male and I recently started to experience chest pain in my the middle of my chest when I really start pushing myself really hard. I am in good shape and exercise regularly and could push myself very hard before with no problems. Any ideas to why this is?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more due to work out and exercise. But better to get done ECG and 2d echo to rule out heart diseases. If both are normal then no need to worry heart diseases. Musculoskeletal pain is more likely in your case. So follow these steps for better symptomatic relief. 1. Avoid movements causing pain. 2. Avoid bad postures in sleep. 3.  Avoid heavyweight lifting and strenuous exercise. 4. Take painkiller like ibuprofen. 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.
