Thanks for using health care magic for posting your query.
I have gone through your given history in detail.
From your description it appears that you certainly have a raised BP recording. Stress
does increase the BP but its mostly the systolic BP which increases and not a diastolic as in your case. So it is unlikely cause of the stress.
You should take BP measurement on 5 consecutive days in a resting state and make a record.
if it is still high, you will surely need BO medications.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
