[|Human|] I am a male, 29 years old, athletic, and in good health.  For the past two years, i have been experiencing a dull pain in my chest on the left side after i have been sleeping for some time, and sometimes the pain radiates through the middle of my back.  Ive checked many forums, and have yet to find out anything.  Ive also had xrays with normal results.  any thoughts?  i do not have GERD or any sort of acid reflux.  I want to look into getting an ECG, do you recommend i start there?
[|AI|]  Hello! Thank you for your question on Chat Doctor! Regarding your concern, I would like to explain that your symptoms don't seem to be related to any cardiac disorder. The most probable cause would be a articular pain, from a thoracic disk disorder. I would recommend a careful physical examination and a thoracic spine x-ray to exclude this. I would not exclude also a musculoskeletal pain and an portal disorder. Furthermore, I recommend performing a cardiac ultrasound, which would help examine the aorta better. If all the above-mentioned tests result normal, the most probable cause would remain a musculoskeletal pain, from a wrong position during sleeping. Hope to have been of help! Best wishes,
