random morse code like ringing in ear?

Over the past few days I have had a sudden morse code like ringing develop in my right ear, I've always had tinnitus but it was very faint, I could barely hear it, but this is LOUD, like almost deafening

Its like a typewriter or morse code, high pitch then low pitch, I have always treated my ears pretty well, never listened to loud music, why is this happening to me???
