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.
