I woke up a few days ago, and i found a small lump on the right side of my neck , right above my colorbone, its about the size of a dime, when it first came up it was a little smaller, and caused stiffness to my neck for 2 or 3 days, the stiffness is gone today, but the bumb is still there, you cant see it unless i tilt my head to the left and point it out but you can feel it. Im a 12 and a half year old female , 5 foot 4, and 156 pounds i dont smoke , or drink and i still havent had my pieriod
