I Feel A Pain In My Chest On Left Side,
Please get an ECG done
Hello and welcome to Ask A Doctor service.
Any left sided chest pain should be investigated for any possible heart problem. I will suggest that you visit a doctor urgently and get ECG done and read. Another test that would help is chest XRay PA view for any other chest problems. A repeat thyroid profile needed. An internal medicine specialist or cardiologist to be consulted.
Hope this helps. Let me know if I can assist you further.
