Hi
@Janice Miller - firstly, welcome to our wonderful forum. Nice to have you on board!
So, you say your tinnitus started 15 years ago. The first thing is to ask if you were going through a stressful period in your life when it began? Or whether you have any hearing loss? Perhaps you were exposed to a loud sound, or on any type of medication (though I know you said you don't really take any). Have you suffered any kind of injury to the neck/head/spine? Or do you have any jaw issues?
Of course, what I have listed above are some of the main causes of tinnitus. I'm pretty sure there are many people on this forum who have no idea what caused their tinnitus. So I guess, for some people, it will always remain a mystery.
As to what might lessen the problem, well unfortunately there isn't much out there at the moment. I personally try to stay distracted, and keep as fit and as healthy as I can be. Regular exercise keeps some people's tinnitus lower in volume. Others have had some success with dietary changes. Obviously good sleep is a big factor for many people who often find their tinnitus is louder if they don't sleep particularly well. Some members have even had various success with a complex of different vitamins.
If you have a read through some of the threads on here, you will begin to get an idea of what different people have or not had success with.
Anyway, I'm not the best person to inform you. I've only had tinnitus for a year and a bit. But I'm sure lots of lovely people will respond to you soon enough Janice.
And if you feeling down about the tinnitus, just have a good rant on here. We're great listeners considering we all have problems with our ears - ironic hey!
