It could be as simple as lymphadenopathy associated with a viral infection, or as complex as multiple lymph node involvement from one of a variety of lymphomas.

Im a med student. I am NOT a pro yet. but here is a possibility: a hematoma (blood pocket). You say no trauma, but do you play sports? racket sports and basketball (where there is lots of changing of direction) can cause muscle tears which may allow bleeding into muscle, within the fascia. This results in a localized swelling which can be painless. The hematoma will last long after the muscle seems to be fine, as the blood lump will take a long time to be broken down. You dont need to have blunt force trauma to area for this to happen. I recommend you see a doc though, I don't have a medical license, and I haven't examined you. They may send you for an ultrasound (the most painless and noninvasive test in existence) to see what is inside.
