We as humans have a tendency to look for patterns, for links. Sometimes we search for them almost desperately habitually. And sometimes - in the case of links to negative physical responses - our brain/body also works behind the scenes, automatically, to try to quickly find links to things it thinks are dangerous.
So, for instance, take food poisoning. Eat a meal of steak, potato and strawberry, get a terrible bout of what you believe is food poisoning, and some people will lock onto strawberries and never eat them again. Was it the strawberry? Maybe. Was it the steak? Maybe. Was it even food poisoning? Maybe.
But now your life is led without the joy of strawberries, forever.
This is what appears to be going on here with BrStan and his driving/tinnitus link, and this is also what linearb is fighting against when he says correlation isn't causation. Did the tinnitus increase while BrStan and gavr were driving? Yes. Does that mean driving caused it? No. It could have been the MRI from 4 weeks ago, or the increased stress at work, or the strawberries. We know that tinnitus goes up, down and all around for a multitude of reasons. The type of thinking that definitively links a T increase to driving, because it happened to increase, once, while driving, is the type of thinking that is going to drive you to an anxiety disorder.
Does that mean it *wasn't* the driving? No, it doesn't mean that either. It always *could be*. But the point is: be very wary about linking two things together difinitively after a one-time correlation between the two. That type of thinking is what nourishes superstition and OCD.
