I have had a lump on the right side of my neck since I was 4 years old. I am 28 years old as of today! I went to a ENT a couple of years ago and he did X-rays. I forgot the actual diagnosis but I do know it was not a lipoma . The vein only bulges out when I am laughing, talking loudly, or singing. I am getting to be very conscious because sometimes it gets a little sore when touching. The doctor actually says that it is a part of my vein and that there are actual blood vessels going through the lump. Do you know what this could be?
