Lump on right side of neck

Patient: On the right side of my neckc there is a lump. I didnt even know there was a lump there until one day I twisted my neck to the side , I dont know why, and then felt it there. It is only feelable when I turn my head to the left. It doesnt pop out. Its not big, It can move and when I touch it it doesnt hurt, I have no symptoms or anything wrong with me. I kind of think it has to do with acne i dont really know.

Symptoms: None
