I don't know we're to start feels like my vision is messed up I have pressure in my head my stomach is in bits my head feels like it's going to explode and feels like someone is stabbing me in one place comes and goes but hurts
I have that too 
The head pressure and weird vision is the worst I always fear that I have a brain anuerysm
Yeah that's what makes it worse over thinking but I have a lot on my mind at the moment so not good that's why I am like this it ain't good
I get the pressure in the head too, also feels as if its going to explode, it just happens for no reason, i was ok today and then this afternoon it started. Try to relax, its very hard to do that i know.
Sure is hard lol I haven't had this in a while I have been over thinking and it's been going around and around I know it's anxiety cuz it comes and goes I get some sort of earache that comes and goes now have neckace also
Its tension in your head that causes this, i have had it on and off for years, i just learned to accept it but it does affect your life. You are having a bad day just try to clear your head of bad thoughts, its not easy, i talk to myself and tell myself not to worry it will pass, doesn,t always work but anything to help the situation.
