Is it normal to feel tingly?

This past year, I have felt tingling in my fingers. I don't know why. It doesn't happen too often but its happened a couple times in the past month. Before that, I think its been half a year since my fingers tingled. When I was in eighth grade, parts of my body tingled from being near a boy i had a crush on but this year, the fingers aren't tingling because of being around an attractive boy. I am eighteen years old this year and am a freshman in college. I was told that I could have diabetes. I've never been tested for it but I suppose it is possible. And I just found out last weekend that on my dad's side of the family, I have a family history of diabeetes. I'm also thinking that maybe my circulation might be getting worse. Anyways, I'm pretty sure for whatever reason my fingers sometimes tingle, it is bad.
