Hi dear
Welcome to HealthcareMagic.
Off medicines , blood pressure can shoot up.
High blood pressure shows symptoms like headache ,
dizziness .The
chest pain you are experiencing could be any cardiac origin or due to
hypertension or due to spicy food you ate causing gastric disturbance.
I advise you to visit a Cardiologist , get a regular cardiac checkup done to be on safe side.Please donot skip hypertension tablet , when you skip accidentally , eat salt less food that day.
Take care.
