<s>[INST] Hi Doctor, 5 months ago I fell on my back awkwardly while playing basketball and ever since the center of my chest has been hurting whenever i do activites, i can reduce the pain by popping my chest but it never goes away, what do you believe may be the problem? [/INST] Thanks for your question on HCM.In my opinion it seems muscular pain only but since it is chest pain, we have to rule out cardiac causes. So better to get done ECG first.If this is normal than it must be musculoskeletal pain only.And chances of musculoskeletal pain are more as you are having trauma history.Try to follow these for musculoskeletal pain.1. Avoid heavy weight lifting.2. Avoid strenuous exercise. 3. Avoid bad postures in sleep.4. Take good painkillers and muscle relaxant.5. Apply warm water on affected part.6. Wear chest belt so that minimal movements occur. </s>
