Advice on the effects mobile phone masts have on health

[this modern lover]

Hi

Not sure if i have posted in the correct area??

Ok where i work there are 2 mobile phone masts on the roof T mobile and Orange.

I have been at my place of work for 7 weeks and have recently noticed a major increase in the following:

Headaches daily (usually when at work and subside when not there)
Dizziness
Lack of concentration, finding things hard to understand.
Tingling in my head and sometimes in my arm.
Generally low in myself as if my immune system is struggling.

I am not the only member of staff that has been have bouts of bad health other collegues have had the same symptoms. One actually visited the doctor for blood tests only to be told he was fine?

I am generally pretty healthy.

I am concerned that these masts could have something to do with this?

Could anyone point me in the right direction to gather some information? As i haven't a clue where to start.

I am actually beginning to dislike my place of work and feel now if something is effecting my health i should leave!

Thanks in advance.
