[|Human|] Hi, Im a 19 year old boy and I have been experiencing weird feelings n my chest lately. I first noticed this after a workout 2 nights ago. During my workout I felt as if I may had pulled my sternum muscle, but would that make my chest feel heavier, or make it seem like my heart is beating louder?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Pulled sternal muscle can not cause chest Heaviness and heart beating louder. In my opinion, we should first rule out heart diseases for your symptoms. So get done ECG, 2d echo and stress test (trade mill test). If all these are normal then no need to worry about heart diseases. Sometimes, stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. Apply warm water pad on sternum. Take simple painkiller and muscle relaxant Chat Doctor.  Avoid heavyweight lifting and strenuous exercise. 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.
