Lump below tge ear/swollen lymph node.

Today i found this swollen lump about 1.5-2.5 cm in diameter below my left ear. Its not hard to touch, sort of rubbary and it does move when i push against it. It is visible to the eye. Its visible when i bent my neck. I feel its a lymph node... I had a minor throat pain two days back its not there anymore. My left ear piercing is also slightly painfull, Could this be because of that. It could be swollen lymph node? I had a complete Cbc done few days back everything was normal. Along with KFT and RA factor test. I have a high RA and anti ccp. However i am not on rhumatoid artheritis medication because the rhuematologist said i have symptoms. I also had swollen lymph nodes before in the same side before accompanied by my piercing getting slightly painfull, oozing water and crusty.  But it decreased in swelling on its own. I also have gingivitis and a history of peridontitis. Will this go on its own, should i get it checked immidieatly or observe  for a few days and
