Could I have high blood pressure?

Hey I'm 19 years old and was thinking I might have hypertension...for starters my uncle had a heart attack when he was 16. I personally don't work and pretty much just drink all day. I sometimes find phantom bruises, which I heard is a sign of renal failure. Also sometimes i get these weird flashes of light that looks like little ants scurrying around in front of my face, and right now the left arm feels weird like the veins hurt and the blue ones on my wrist look like their bugging out. Anyone know what's up?

No, you can't. The effective ('mean' or RMS) pressure generated by everyone's left ventricle is roughly the same, the small differences being only body-mass and build.

It (the mean pressure) can be calculated very accurately by multiplying the amount of blood pumped out by the heart each minute by the total impedance of the cardiovascular system. Same as Ohm's Law in electrical theory.
The average blood flow of a normal adult is about 5000 millilitres/minute and everyone's TPR (impedance) is roughly 0.025, which gives a mean (or RMS) pressure of
125 mms?hg.

That's the true blood pressure you have, -although you can't measure it with a monitor.

The readings you get with a monitor cannot possibly be your true blood pressure and the whole, monolithic Hypertension Industry is based on the fallacy that it can .

Pathetic really, -isn't it? And really, .... quite unbelievable! You couldn't make it up.

You can check the link below to look up your blood pressure and see if it's normal.

Yeah, so, go to the doctor. That is going to be the only one who will be able to tell you what is wrong with you. Definately not describing normal things to be feeling, get it checked out.

You drink all day. If u mean alcohol which i think u do then try to stop drinking for a while and see if there is any improvement or the symptoms go away, if not then i dont know.
