It sounds to me like you should be on a medication, such as a beta blocker, to lower your blood pressure. From what you posted, I assume your doctor did not prescribe any medication.
at your age, it's probably hormonal - which might also be directly causing those feelings/symptoms
how high does your BP get? people don't normally feel BP unless it gets very very high
Thank you for your answers.The BP usually gets 140/80 anyway i have been taking some vitamins only,because i have asked some people and they have told me that would pass so i'm waiting.
