Feel like there is big knot in carotid artery feels swollen beats hard. can't see doctor till monday family won't let me go to er ?

Just answered: Can't see a swollen carotid artery. You should be fine till Monday. Hurtful not harmful

Carotid body: Yes, that's a structure of the human body that serves as a sensor that makes sure the brain gets blood (and therefore oxygen). That beating you feel is the 'pulse' - and I assume you have a thin neck, which is why you can feel it so well. I don't think you need to go to the ER for that -- it would be a waste of your time. If you're still unsure, a regular appointment with a family doctor is OK.
