Dizziness and pressure in head

Hello, I'm a 13 year old (girl) and I seem to have a problem with my brain, and thought I'd come here to ask you about it.

I haven't been to a doctor since i got the flu when i was like 6 years old, and my family probably won't be able to take me to a doc any time soon because of how expensive it is, so i figured a web doctor would be the next best thing.



I know it's normal to get a little light-headed after standing up, but I seem to
get this pretty bad.

When i get up, my brain sort of blacks out for a good 5-10 seconds. I can't think at all, it feels like my brain just swelled up and is now pushed into the side of my head, my entire thought process just sort of stops, and my vision turns black, and blurry. I'm forced to just stand there in place for awhile and grab onto the nearest object to avoid falling. This has been happening since i was about 9 years old, but it's been happening more and more often.


This next problem is quite new, and has only been happening for a few months, if i remember correctly.


A lot of the times when I'm just sitting down, or doing anything really, my head feels like there's a pressure on my brain, like right now it feels like my brain is getting pushed into my skull. My head has currently been feeling like this for a few hours, and I haven't been making any sudden movements.It doesn't hurt, but god it's so hard to think, i sometimes want to pull my hair out of my head because of how frustrating it is to not be able to get rid of it, i just want to slam my head into a wall. It is making something as simple as writing this sentence hard, and i feel like having to think for any length of time is almost physically painful.

This doesn't happen as often as problem #1, but I'm worried because it is quickly getting worse and happening more often.


It seems the getting dizzy and fainting thing is a symptom of having very low blood pressure, but my brain being squeezed happens when I'm sitting down or have been standing for a good while, i don't have to make a sudden movement for it to happen.

By the way, my family seems to get dizzy to, but I'm not sure if they get this as bad as me, and they don't get that 'pressure' in their head, I'm quite certain.


Is this very dangerous for my health, do you think?




Sorry for the long post
