I found a very small hard moveable lump on my Adams Apple on my hyoid bone, and I've never noticed it there before. It feels almost as if it is a piece of cartilage or bone. It almost has a singular, rectangular feel to it like a small tube, not circular at all. Like I said, it is very small no longer than the tip of my fingernail. I have no other symptoms or weight loss. I might be scaring myself and this might have always been there, or part of my Adam's apple. It feels like this is a part of my Adam's apple, but I don't know. I suffer from extreme health anxiety, and it eats away at me every single day. I am 24 years old. What should I do? Can anyone give me insight, please? Thanks
