I was randomly feel my right above where my throat begins, above the adams apple and I felt a little bump/cyst (?). It's on the left side of my face only and it feels weird when I touch it. I can sort of move it around, but only a little bit. It feels hard and I'd compare the feeling of it to that of a small marble (the smallest marble), or maybe a bb or even a pellet. I'm concerned what it may be. Any help would be greatly appreciated.
