I have a swollen lymph node on top of coroided artery right side. doc said its ok but i am always pushing to feel it. will pushing on arteries kill me?

No: If you push on both sides at the same time it can make you pass out, but casual pushing on one side will not hurt anything.

No: However, this should be evaluated to make sure that it is not a tumor on top of the carotid (carotid body tumor). This can be evaluated with a simple ultrasound test of the arteries. Pressing on the arteries can cause lightheadedness, and could be dangerous if there is plaque or blockage in the arteries.
