pea sized lymph node feels attached to jugular

I've had a pea sized lymph node which feels attached to my jugular for about a month. There is some slight puffiness around it but It doesn't move!  I noticed it after having a crown on an upper tooth.  I have slight sinus-like symptoms that come and go during the day making me think I have an infection that can't quite develop to full-blown capacity. At that time I get a runny nose.  One day I noticed fluid in my ears by putting my baby finger in but that is no longer the case. Once in a while I feel hoarse but don't feel there is anything draining in my throat.  I am very concerned and am nervously awaiting my dr's appointment.  Can anyone help?
