Hello, thanks for the "questioning".
Only complaints you mentioned are sweating, dizzy, pain below breast area.
Before we reply tell us your age since you mentioned breast area in your query so it seems you are a woman.
If your's age is more than 50 yrs ( round about). the diagnosis is different, if your age is 30 yrs than we have to diagnose accordingly.
Ant way broadly speaking , if you are not near menopause
than deal according to age as this may be due to this. If young ( really) than it may be a case of anxiety
, over work, gastritis
, excessive fried food.
So please take care and be healthy. Dr. HET.
