For some reason, I'm always worried that my gums are getting inflamed and are too big. To counterract this, I pick my gums with a needle or unbent paperclip or any sort of thin metal object. However, I've noticed recently that I've got 6-10 needles next to my computer, and whenever I'm sitting here, I'll find that I have one in my mouth, picking at my gums, whether or not I remember putting it there. Is that normal?
