question: Hi. last several days Ive noticed the left side on bottom jaw is swullon pretty sure its a lymph node bout the ipsize of a quarter moves around like a ball slightly tender more noticable when i turn my neck but. only on the left bottom jawline.  Infection? I do suffer from allergies and as of two wks ago had a steroid injection i am positive it has nothing to do with bad teeth or gums i have been feeling rather dizzy last several days and runnning low grade tempi have had vertigo. my eyes would rapidly twitch and full blown head spinning feeling along side with facial spasms and often get swullon eyes and eye headaches.
