My problem started around 6 months ago. I do office work, so I spend from 7 to 10 hours in front of the computer. I don't know if the type of screen has anything to do with it, but I use a MAG flat LCD screen as well as a laptop with LCD screen and I have the problem with both.

I never had any trouble before while using the computer for long hours. The first time I had this was at the end of a work day. I just felt very dizzy, although it was more a feeling of being "spaced out", or an "unreal" feeling. The first time, it happened after leaving work, not while I was at the computer, so I wonder if that is the real reason.

After that, I've have good days and bad days, although bad days seem to be increasing. Sometimes I just get very dizzy when working at the computer, and it goes away after a few minutes of doing something else, but other times I have this "spaced out/unreal" feeling for hours after work, or even the next day. The feeling seems to increase when I am in crowded / loud places. I also think it could have something do with stress, or a combination of all factors.

I also have allergies, I have skin rashes and itching, but no respiratory problems. The allergies may be food-related, but I haven't been able to find which food causes them.

I have been reading and I see there are many explanations for this kind of thing, from the type of computer screen to fibromyalgia and chronic stress syndrome. But I don't suffer any muscular or joint pains as described for these diseases.

I would like to know if someone can offer some professional advise. I would really appreciate it. It is very scary and I have no clue what to do.
