Just a quick answer to one question since I am getting on a plane. Nodes from infections hurt, are tender. Painless nodes are the dangerous ones. You have a tooth abscess that drains into the cervical nodes or an ear infection that is being cleaned up by them, those noes are really tender to the touch. When I found my own cancer...(everyone that had been looking at me for a year missed it) I could flick the swollen node with my finger and felt nothing. No pain. That is the give away that these are something not so good. Seems like the members are taking good care of you, will check again tonight when I get on the ground, and in the morning before my lecture to see if there are any unanswered questions.
