I have discomfort around the area of my jugular vein. it comes and goes as it pleases and has been happening for two days. what could this be?

Doctor can evaluate: A primary care doctor or an ENT doctor can evaluate discomfort in the neck near the jugular vein, if the symptoms persist or are worrisome. If a person is young and healthy, the discomfort is likely from an inflamed lymph node, since there are many lymph nodes in the neck. Such "reactive" nodes go away on their own. So, if symptoms don't go away, one should be checked for the more unusual causes.

Normal: Neck veins distend when we lie with our head lower than our heart or when we strain. With straining, the pressure within the chest increases and the blood flow through the neck veins decrease resulting in them enlarging. This is normal. Levels of hydration, genetics, outside temperature and any increase in pressure within the chest will enlarge the neck veins. Your veins are most likely normal.
