Hi
All your symptoms can be caused by anxiety, i have had 14 months of similar symptoms, but my inital symptoms were related to an inner ear problem. One day i started feeling dizzy at work and then my balance went funny and all my problems started. My symptoms include headaches, tight band feeling around head, facial pain, cheekbones aching, chronic stiffness around back of head/neck, sore scalp, pains around top of the head, ear pressure, tingling in face area, many visionary symptoms including floaters, inability to focus on things for long peroids, eye pain, itchy eyes, watery eyes.
I think whats happened is my problems started out as a physical problem (inner ear disorder) which i had for about 8 months and then anxiety just took over so most of my symptoms now are related to anxiety and the fact i was straining all my muscles, especially in head and neck area when my balance was off. Its amazing how much you take your balance for granted, all of a sudden i couldnt stand up in a busy place cos i was scared i might fall over, its very hard to deal with. Im 29 and used to lead a very active lifestyle but the whole anxiety thing along with all the symptoms can seriously effect your life, well it has in my case.
I have seen 4 ENTS, a neurologist, had balance tests done, had MRI scan and nothing has ever really showed up. My problem is dealing with the anxiety, i have found this a real struggle and i am being referred to CBT therapist to help me.
Also its interesting you mentioned getting dizzy spells on the computer, i nearly quit my job in the first 5 months as i couldnt stare at the screen, im a designer and am on computers all day and with the dizzyness and headaches it became unbearable. But i have gotten used to this, but i talk from experience when i say being on computers is one of the worst things if you suffer from dizzyness, head pressure and headaches. Also sometimes my eyes cant cope with the screen, in fact most of my symptoms occur when im at work, so it can be a real stuggle!
I hope this helps.
