Thanks for your question on Healthcare Magic.
I can understand your concern.
Since you are having left sided
chest discomfort, better to first rule out heart diseases in your case.
At your age of 59 years (post menopausal age), women are prone for heart diseases because of low
estrogen and
progesterone.
So first get done ecg, 2d echo and
stress test (trade mill test).
If all these are normal then no need to worry for heart diseases.
Sometimes stress and
anxiety can also also cause similar kind of chest discomfort.
So avoid stress and tension, be relax and calm if you are having stressful life.
Don't worry, you will be alright. But first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
