Need to evaluated by an ENT specialist

most likely a lymph node. These can get inflamed and swell at any point in time, usually in response to some sort of inflammation. Sometimes they will shrink back down, sometimes not. As long as its not progressively growing, its likely fine. Bad lymph nodes will get hard and become 'fixed'.
It could also be a type of congenital cyst, such as a branchial cleft cyst, depending on where it is on your neck. Either way, a simple neck US can evaluate this for you. But if its not growing or painful, likely its a common lymph node.

A neck mass certainly warrants evaluation. Please see an ENT doctor for a work-up. Based on its location and your description, I would bet it's likely a lipoma - a fatty tumor.

Most likely benign. Lipoma or inclusion cyst, could be branchial cleft cyst as well. Have ENT look at it
