RINGING IN MY EARS

Oh. My. Goodness. 
The ringing in my ears is driving me insane.
I'm having a difficult time hearing anything BUT the ringing!!
I haven't gone to a loud concert, suffered a fall, listened to music with my headphones too loud, etc.
It just showed up one day like a big, loud present of CRAP.
How does this happen?? What do I do to make it stop??
