Thank you for your query at DoctorSpring.com
I understand your concern.
Do you have any history of cardiac ailments in the past? Any history of hypertension/ diabetes mellitus?
You also need to get your BP checked, because high BP can lead to dizziness coupled with feeling of nausea/ vomiting and headache.
So it is better you get your BP evaluated and then take a decision.
Feel free to discuss further,
