so, this is how my story goes: i am 30 year old female. i have been diagnosed with asthma when i was 15, since then i have been having problems, but for the past 3 years asthma is under control since i have been on seretide 250 mg. i also have nose polips and chronic sinus infection. my nose was runny for 3 yers or so, but since i am using one drug containing budesonide i am ok, my nose is not runny anymore.
so , here it is what's bothering me. from time to time i have this strange symptoms: i feel very lightheaded, i have some strange foggy feeling in my head, usually no specific headaches, just some head pressure between my eyes and on my forehead.
i hate that foggy feeling, 'cos it makes me feel very blurry, like i am in a twilight zone, that i cannot concentrate well..
the first time something like this happened was 2 years ago when i had my first migraine attack, and then after the attck passed, i was feeling foggy for week or so. but now, when this fogginess happens, i don't experience migraine headache, just that pressure on my forehead that i was talking about.
besides that, i don't get any vertigo, i wouldn't say that i have that usual dizzy spells, it is just that i sometimes feel unstable in my head, like i am on a boat or something like that.
also i would like to point out that i am a serious worry person, i worry about everything, i am also hypohondriac and the smallest thing is a misery to me

during past years, due to some emotional and family problem, i have developed some anxiety problems too - stomachache, stomach neurosis, non visible shaking from the inside and headpressure.
one other thing - i have developed some neck pain lately due to bad posture. i am shortsighted, i wear contact lenses, sometimes glasses, i don't see much without it

so , while sitting in front of pc, i automaticlly go forward, to see the monitor better, which is causing my neck pain.
so, here is my question: my head problems (foggy feeling, lightehaded, dizzy) - could there be a result of chronic sinusitis, even though i don't have runny nose, nor any other symptom of sinusitis, besides high forehead pressure. or, these sypmtoms are also a result of my anxiety, or even neck problems and bad posture? or, the worst option of all, is this isolated symptom which should be treated? remmeber, i am a hypohondriac, so i am thinking about all other terrible things.. MS is my fave immaginary disease heheh

fogginess is the thing that worries me the most.
sorry for the long post.. hope someone will be able to help me
thank you
