what could cause constant dizziness that lasts for months in a group of people that work together

[Kabees]

Back in January I became dizzy (non-spinning) very suddenly. I was at home when it happened and the dizziness never went away and all these months later it's still going strong. I ended up going to the ER right after it started and they did ECG, blood tests, etc, and nothing abnormal was detacted.
When I returned to work a day or so later, I discoverd that another woman in my office came down with the same exact symptoms as myself, on the same date, and she too has been dizzy ever since.
I went to 2 ENT's and all tests were normal except a caloric test and balance test done on me showed problems with my vestibular functions but no cause could be determined. I don't have any ear discomfort or allergy symptoms at all.
I had an MRI, this was normal.
My dizziness fluctuates throughout the day, and seems worse while I'm sitting upright and still. My coworker's dizziness fluctuates as well, usually in correlation to mine.
My coworker thinks it's allergies but I'm not really convinced. She is taking a variety of meds for allergies and she hasn't improved.
Is threre any clue as to what this could be? This is so strange to me and it's really ruining my life, I'm not sure what it could be or what to do now.

One question I have is if this were a sinus related issue, would the brain MRI with contrast I had have shown any sinus troubles?

Hi
Welcome to the MedHelp forum!
If this co-worker and you sit very close then *** could be airconditioner causing mold related symptoms. It could also just be a co-incidence if only two of you are involved. It could also be that both of you suffer from vasovagal attack. If you work in some sort of chemical environment then it could be the effect of chemicals too.
Hope this helps. It is difficult to comment beyond this at this stage. Please let me know if there is any thing else and do keep me posted. Take care!

I am new here so don't know the rules on posting twice.

The title says 'Group' of people either you said that to get more veiws or There are more than just you and your co-worker experiencing these symptoms ,Because if it's more than just you 2 ,Maybe it is linked to mold? ,But you also say it was the same date she got the symptoms. Seeing that both of you came down with an inner ear disorder on the same day and same symptoms is very unlikely unless it is viral or bacterial.

I would say a Inner ear problem(Balance Disorder). A balance disorder may be caused by viral or bacterial infections in the ear, a head injury, or blood circulation disorders that affect the inner ear or brain. Does the dizziness go away while you are driving? I can't think of the name for it right now ,but There is a part in your brain that tells itself when it is moving. Usually seen in people who get on a plane and get off ,The part in there brain never stops and tells them they are constantly moving so they are always dizzy ,but Seeing how you got it out of no where that rules it out. This is very odd that your co-worker has the same symptoms.
