I have what feel like a rope in the front of my neck slightly off to the left side under my chin. I can see and feel about an inch of it when I lift my head up as if looking at the ceiling. It is vertical and looks tight. If I relax my neck while looking up it disappears. It's been there for a long time, maybe as I was growing up but have now developed health anxiety so I guess I'm noticing things I wasn't before
