Are these weird urges/ obsessions/ bad habits?

I have two random urges/ obsessions/ bad habits...

For one, I always feel the need to take pointy objects (but nothing that could really hurt me... something like a pencil, a pen, a crochet/ knitting hook, etc) and push it into the middle of my pointer and middle finger on my right hand. I do it between some of my other fingers but it's mainly between my right pointer and middle finger. It just feels slightly itchy or tingly and I feel the need to stab it with my pencil (or another pointy object.)

Also, a hair-twirling-and-chewing obsession started this year. I always feel the need to brush/ stroke my hair on my left side... never the right, unless it's a beauty emergency ;) Well anyway I stroke my hair until it's soft and then I take a nice soft piece, twirl it around my finger, and chew it a little. I do it in school sometimes but not too much because I don't want people to see me doing that. I should also mention that when I'm twirling my hair on my left side, I pull it really tight to satisfy the 'itch' between my left fingers.

So far as I can tell it's not harming my health, but I just think it's weird that I do those things so much
