From your experience, do you know what that pressure is? Do you know how to make it go away? Do you know anything at all? Or are you just going to tell the OP to see a doctor? Like, are you guys able to contribute at all?
Uh, yeah.
Feeling head pressure or a headache is super common, and people of any age or physical condition can experience pressure in the head. Caused commonly by an inflamed or infected sinus (which is known as sinusitis

To me? This shit is common sense, man. You got a health problem and you don't know what it is, you DON'T (I repeat, DO NOT) go on the internet to ask help on a drug forum from a pool of people that might include one who seems to take pride in his intentionally-induced psychotic episodes at 3am, and even more pride in dispensing terrible advice that could hurt people in the long run despite the fact that what you're saying is basically "Don't worry about it, go get your dick wet and you're cured."
Like, FUCK, man, how can you not see how retarded a person who actually cares about the well-being of the average person here might find that kind of thought? And then, coupled with the pride that you seem to take in inducing psychotic thoughts/hallucinations with amphetamines and the way I've seen you gloat about the facade that you can have some sort of control while you intentionally FUCK YOUR BRAIN OVER WITH SPEED, it makes me think that you're just not the guy to give medical advice, man, and it has nothing to do with your experience but everything to do with the way you seem to think and the actions you claim to take.
And maaaaaaaaan, I tried to leave this conversation so as not to think any less of you and to let you do your thing. You pretty much just fucked that up completely with your incredibly passive aggressive post.
Sometimes you should let people do that (walk away, I mean.) It might work out better for you in the long run, because, Ksa, and I assure you of this: you're clearly not as smart as you think you are. That's another common problem really, but I've never suffered from it. My problem is I'm not as stupid as I tend to think I am-- whole 'nother bag of worms, to be honest.
