3 Weeks Of Consistent High Blood Pressure (Taking Propranlol)

[TheShinyOrange]

Hi,I'm 24, I'm new here so sorry if I miss anything out or show my lack of experience. I've for the last 3 weeks had blood pressure ranging around 140-150/77-86 I've been having many symptoms 24/7 including severe headaches, dizziness, bloodshot eyes, fatigue, lightheadedness etc. I've been recently prescribed propranlol (been taking it for roughly 12 days) by the doctor I take 40mg in the morning and 40mg in the evening. I've not noticed much improvement. My eyes are really blood shot which concerns me, I've seen a optician's 2 days ago pressure behind eyes is okay, but they can see swollen blood vessels. How long did it take for others to improve? I just constantly feel drained and it's taking a massive toll on me physically and mentally. Thanks.
