I would goto your doc, and get it checked out. I am in the same boat as you I have 3 small children, we do have insurance but I stay at home with my children so money is always tight. I have found 2 swollen nodes under my jaw that have gottena little bigger with time, my DH told me to ignore them too. I just couldn't do that. I figure its better to find out and start treatment right away if I do have it, I DO NOT want to leave behind my small children.
From everything I have read about hodgkins and non-hodgkins is that there are two forms of lyphoma one is non NHL(non-hodgkins lymphoma) the other is HD (hodgkins disease) They both have the same symptoms. The ones you are discribing, itching weight loss, and a painless swollen lymph node. HD is the better of 2 evils, it is curable and has a very high % of survial. NHL on the other hand seems to be a little tougher.
I would see if you can get in to see a doc, and see what they say. I will be getting my nodes biopsyed ASAP.
HTH!
