About thirty minutes ago, I had the strangest thing occur. Both my ears began ringing, and nothing seems to make it stop. I haven't a clue what could have precipitated this, since I haven't been exposed to any loud sounds prior to this occurring. As a hypochondriac, I probably shouldn't have Googled it, but now I'm wondering if this could be caused by hypertension. I've never had blood pressure issues before, but recently, when giving blood, I've been told that it was a little high.
