Ringing in left ear.

For the last few days my left ear has been ringing. My mom, My moms sister and My grandfather all have ringing in their ears/ear... I've had alot of ear infections in my left ear too...Should I worry about this, Is there something seriously wrong with my head, Do I have a brain tumor or a brain aneurysm?  Im only 15. Im not sure if alot of 15 year olds have brain tumors or brain aneurysm's.

If you have had a lot of ear infections I hope you have gone to an Ear,Nose and Throat doctor.

You may still be getting low grade infections or have other inner ear problems that may need to be more thoroughly checked out.
I have ringing in my ears all the time and believe it is nerve related.  I drives me up a wall at times.
You are much too young to have to put up with it so have your folks have it further checked out.

I experience ringing in my ears quite often.  Mostly the right ear,  when I am feeling that tingly feeling all along that side and,  sometimes in the left.  As a kid,  I KEPT an ear infection and most of the times it was in both ears.  I cannot help but wonder if what I am experiencing now is due to some type of nasal allergy or an inner ear infection that I'm not aware of.
