I have suffered with searing headaches for years and can attribute them to wireless technologies ranging from the Wii games machine to wireless routers (Experts raise health concerns over Wi-Fi).

Wireless routers and associated network devices cause me great pain. My employer did some blind tests on me and I can pretty well predict when the radiation is switched on. I have been to the doctor who has referred me to a neurologist. But I am really concerned. What is discouraging is the way this condition is laughed off by so-called professionals. If I can sense wireless signals - what are they doing to our bodies?
