I have this strange ropey thing running from my clavicle up through that empty space between the collarbone and shoulder and up to around the back of my neck. It's only on one side and I can't find anyone else with it. It's most visible when I'm sorta shrugging to push it outward. It doesn't hurt and feels kinda thick. I don't feel a pulse from it so I don't think it's a vein or something like that.
I can't remember if it's always been there or if it's new, but I think it's new-- I would've noticed it before. What is that? Is it something I should be worried about or am I just being stupid? Thanks for your help!
