All of these symptoms sound alot more like anxiety/panic disorder than symptoms caused by hypertension.
Now don't get me wrong, hypertension is a serious condition but it rarely causes any symptoms unless it is 180/120 or more, and consistent.
This is why it is called "the silent killer". The huge variation also suggests an anxiety disorder. Particularly if that variation involves primarily the systolic.
I'd be curious to see your age, as well as your numbers. Although I wouldn't necessarily believe that your symptoms are caused by hypertension.
I get numbness in my face, flushing you name it. All anxiety, although I do still suffer from stage 1 hypertension "Now under treatment".
The only way to truly know if you are benefiting from your medication is to monitor your own blood pressure. If it is normal, or below 140/80 then the medication is working.
