I could always hear a slight ringing in my ears for as long as I can remember, but it wasn't until fathers day, 2010, that it increased, and trust me I noticed. But that's besides the point, I completely overcame that, I did have shitty days when I kept monitoring my T to see if it was still there, and it was. But I eventually overcame that and it got to a point where it didn't bother me at all, in fact in the years coming up after that I completely FORGOT about it. This year though, it came back. I recently went go-karting (february 13th) with some friends and the ringing increased drastically, I woke up the next day and noticed the increase in volume and thought, oh god not again. I hate this, I thought I completely over came this.
