Thanks for your question on Health Care Magic.
I can understand your concern.
Sudden chest pressure and
blurred vision is indicative of some
heart disease like
high blood pressure, reduced cardiac pumping etc.
So better to first rule out these cardiac diseases.
So get done blood pressure monitoring, ecg, 2d echo.
If all are normal than no need to worry for major heart related causes.
Sometimes
stress and
anxiety can cause similar symptoms.
So avoid stress and tension, if you have stressful life.
Don't worry, you will be alright, but first rule out heart diseases.
Hope I have solved your query.
Wish you good health. Thanks.
