I'm really scared. I'm a fifteen year old girl who has ADHD and depression who has always suffered from undiagnosed headaches. Anyways, I'll get to the point. Recently I've been having extreme pain in in/around/by my carotid artery. No one believes me because of my age, but I know quite a bit about the human body and I know the carotid artery isn't supposed to swell, pulse so you can feel it in your ear, and discolor the skin above it... I also now sweat at random moments and can't turn my head to the right without severe pain. Has anyone had this happen to them? Does it have a name? And how is it treated?
