I have it too - I've had it for a few years - not sure when it started. It's worse when I have a headache - the other day DH and I were in Stonington Boro at the point looking out over the ocean with the car radio off and it got so loud, that it was driving me crazy. I go to sleep withthe TV on and have the radio on at work and in the car.
My headache dr. told me that it could be caused by over use of over the counter pain releivers. I've cut back on those drastically (now I suffer thru the headaches), but the ringing is still there! I've had MRI's and x-rays trying to find out the cause of the headaches, and nothing abnormal.
The Vermont Country Store has a product to releive it - i haven't tried it, but here's the link.
