[|Human|] I am experiencing chest pains - left side specific, for the last 18 hours. No nausea, no sweats, no sense of doom. They began shortly after Unboarding after a 4 hour plane flight.  The pain goes away when I lie on my back or right side. It is worse when vertical or lying on my right.
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion we should first rule out cardiac cause for your left sided chest pain. So get done ECG first. If ECG is normal then no need to worry much for cardiac cause. Since you have this pain after plane journey, pulmonary embolism can be the cause. So get done1. D-Dimer2. CT pulmonary angiographic both are normal then no need to worry about pulmonary embolism. This might be simple muscular pain. So consult doctor and discuss all these.
