What is this pressure under my adams apple?

For some reason I am constantly aware of my pulse under my adams apple. I can constantly feel it pounding. For some reason there also seems to be some sort of pressure beneath my adams apple near the carotid artery. Is this anything i should be worried about? The pressure is kind of uncomfortable, but there aren't any noticeable lumps or anything of that sort.. could it be some kind of circulatory condition?
