Palpable preauricular nodes?? What are the causes?


I am wondering what are the various causes of having palpable preauricular nodes, the nodes that are right in front of your ears? I woke up the other morning and noticed when I pulled on my earlobes, that there were bumps on each side that aren't visible without pulling on my lobes but I can feel them when I do and I tested them by putting my fingers on my jaw/cheek line and opening and closing my jaw and got that clicking feeling.  This is the second morning in a row that this has been this way. I am wondering if this is ALWAYS caused by something viral or can very irritated eyes also produce this affect? I don't think I have conuncitvitis, bacterial, viral or otherwise, because my eyes are not very red, ust irritated and no noticable discharge either. I have a bad dust mite and cat dander allergy, both of which have been very present in my current living situation and usually have itchy eyes at night and in the morning as well as a sleu of other allergy symptoms-sneezing, coughing, chest/nasal/sinus congestion and I currently have lip eczema that has persisted over the last few months (i have a history of skin problems and think it is being brought on by stress.)  I have read that upper respitory infections can also cause the preauricular nodes to enlarge/become palpable.  Besides these things, what commons causes are there for this?  I'm wondering if it is significant that I have had ongoing allergies for a while now and have not as of yet been taking any meds for them.  I am wondering if this as well could cause the nodes to eventually enlarge.  
Any advice or insight would be appreciated.

Preauricular node swelling can be from viruses, allergy, bacteria, cancer, many different problems.  If it's a persistently swollen lymph node, say, more than a few weeks, go have a doctor check it.

Thanks for the info,  I had been under the impression that it could ONLY be caused by a virus as opposed to other things as well.  I have a feeling that letting my allgergies get out of control is starting to cause problems, even with breathing normally...

Thanks again

Out of control allergies can certainly cause lymph node to swell.  Get nasal steroids ans saine rinses and it will help a lot.  If the nodes are swollen more than a few weeks, get them examined.
