Seems more like an infected tooth or infection of the gums spreading into spaces surrounding your tooth and into the lymph nodes. The infection can be controlled using appropriate antibiotics. I suggest you to consult a dentist to assess the situation and prescribe antibiotics. Once the infection is control pus drainage can be done in clinical possible way.

Do you pain in any of your teeth on the right side? If yes, then the issue is most probably because of a decayed tooth which has been infected badly. See your dentist immediately. You will be prescribed a course of antibiotics and the cause of infection will be diagnosed, which will be treated accordingly.
