Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion .
We talk about hypertension if we have mean value that exceeds 140 / 90 mmHg.A person might have high value during emotional and physical strees so its mandatory to judge on mean values during day and night.
There are two types of hypertension : Essencial hypertension or idiopathic, meaning that it has not a definite cause and
secondary hypertension, meaning that it's a secondary couse of it.This is found in younger ages and the cause might be renal , endocrine or any cardiovascular anomaly.
Essential hypertension is a chronic disease and it should be treated all live.
High blood pressure values can give you headache,
blurred vision,
dizziness ect.
You don't mention your age but as I explained above it is essential to exclude secondary causes if you are young.
As you explain you have all ready done blood analyze and they are normal. This is a very good thing.
If I was your treating doctor I will recommend even a cardiac echo, an abdominal echo to evaluate renal structure, your urinary chatecolamins and a holter pressure monitoring.
All these can give a better view of your mean blood pressure values and exclude secondary factors.
If the pressure holter monitoring finds mean values above 140 / 90 than you shoud treat it with medications.
Mean wile avoid excessive salt intake I coffee and energy drinks becouse they rise blood pressure values.
Hope I was helpfull.
Best regards.
