Is the external jugular vein supposed to pulse when standing?

WHen I am standing and I look in the mirror where my external jugular vein is I can see a pulse coming from it only at the bottem of my neck. I have pale skin and If I look hard I can almost see the vein pulsing. Is this normal for your jugular vein to be pulsing while your standing? I know that it does pulse but I thought that was only when laying at 30degree angle or so( they use it for a test to find the jugular venous pressure). When I lay down at an angle and look in the mirror I can see my vein near the bottom of my neck fill up and then collapse like it supposed to do. But when I stand I was wondering if this is normal to see the vein very close to my collar bone pulsing. Is this normal or my jugular vein should not be pulsing because of gravity?

And it is not my carotid artery.

Hello. I know that you probably posted this in another forum but I wanted to make sure that you got the actual answer from me! I think that the issue is probably not much to worry about but it is worth talking to your doctor about anyway just to make sure that it is not a more serious issue in the future. Please let us know what your doctor says!
