Hi Doctor Sukhwinder, you very lucidly answered my queries. Doctor, you are aware of my case. While walking fir a kilometer or so I feel, not pain but, some sort of discomfort in chest-say 2 on a scale if ten. It does not deter me from going ahead with my walk which is normally three kilometers. You can call me crazy but after you, Iconsulted two more Cardiologists. One said that I should undrrgo a stress ECHO followed by Angiography, if warranted instead of straightaway going for Angiography. Theother Cardiologist said my problem is manageqble conservatively. What do you suggest considering the minor discomfort I feel while walking.
