I found this post on another forum and thought it might interest other migraine sufferers. I recently learned I was electro-sensitive and that the radiation being emitted by my portable cordless phone was causing my ear aches and migraines. Cordless phones, like cell phones/mobile phones, emit radiofrequency microwave radiation. Since I've become electro-sensitive, even the towers and antennas in the neighborhood seem to bother my brain.

An excellent thread...

Q: Ear Ache With Phone Use

My husband has been complaining of extreme pain when talking on the phone only. He describes it as a sharp pain that goes from his ear through his brain. This started with cell phone use and now it is with the use of any phone (cell or land line). Does anyone have any idea what this could be?

Found another thread, too...

My migraines are treated by a neurologist in my plan that specializes in migraines. I would like to suggest getting your husband to a neurologist because if this is something that can be remedied, it would be good to get it done before there is any permanent damage. If there needs to be treatment because of a problem with your husband's ear, then treatment could be started and perhaps pain stopped.

A neurologist would give him a thorough exam first and with the problems your husband exhibits, it may be a neurological problem. Good luck and I hope you find the cause.
