Kindly go for emergency ECG
Hello and welcome to Ask A Doctor service.
I have reviewed your query and here is my advice.
Since its deep pain on left side of chest, I will suggest that you get an emergency ECG done in ER.
I can somewhat narrow the diagnosis if you send me details of your pain like exact location, does it worsen with breathing or touching, how does it get better, is it vague or sharply demarcated, etc. Any relevant medical history?
Hope this answers your query. Let me know if I can assist you further.
