I guess I have just itched a lot for my entire life, so I just scratch and don’t really think about it. But it was recently brought to my attention by someone, and I realized that I am scratching constantly. Like all over my body. I’ll scratch my leg, then my head itches, then the back of my hand, then my cheek, then my arm, and so on and so on, every few seconds. I might scratch 10 or 20 spots within a minute. I think I might stop scratching if I’m really focused on something, but if I start thinking about my itching, then it just keeps happening. And like I said, I think this has been going on for my entire life, but I never really paid much attention to it. Is this normal?
Any of the above might be the source of your itchiness. Try keeping your environment minimal and look for triggers
For diet: that’s a tough one, any of a million things you could be sensitive to. You can try a elimination diet for a month and see if that improved your itchiness
Hormonal : this one is fairly easy, assuming your getting all the nutrients you need (check with cronometer) just reduce all glucose sources in your food and your hormones will stabilize
