New worry again!

Hello! Like many of you here, I always find myself worrying about a medical condition. Usually it concerns the heart or gastrointestinal problems, but now I have a weird new symptom. I started being itchy out of the blue ~ 20 days ago on my torso and back. Not my limbs though. How weird is that? I haven’t changed soap, detergent or anything like that recently. I made the mistake of googling multiple times and I saw that it could be a liver or kidney issue, so I’m freaking out. In May, my blood and urine tests were ok. I can’t bring myself to worry about new blood tests in less than a year (I know it’s no big deal for most people, but not for me especially when my HA is bad). And I don’t even know to what kind of doctor I would have to speak to about this.
