Haha. I've had it for as long as I can remember. It's never been more than a "quiet noise" in the background. but if I clear my head and just sit in a quiet place - it's a lot more apparent.
Last time I was at the docs, I told him about it and he suggested that we do surgery. I was like "Uh...no dude. I'm good with it. It's been like that for at least 25 years - I think I'm gonna be ok"
