Well, you likely know that people get enlarged nodes all the time from infection. If your marrow was damaged from chemo years ago, then maybe there's some weakened immunity which lets an ordinary infection escape immediate squelching and so you might get enlarged nodes easier.
If the soreness started near the node and not in the node, that tends to say you're just having a node that's 'reacting' to whatever caused the soreness... which could be the bite that let bacteria in.
Hi, I can speak to that as if discussing NHL, but don't really know how HL might differ.
Did your treatment for HL result in decreased immunity? Any teeth problems? Any stress lately, or is anyone near to you sick?
If the bumps/nodes don't grow, then you shouldn't worry too much because even if it *were* cancer then it being so slow growing it might not be treated anyway.
Pressing too much can irritate and cause some swelling.
Hope that might help somewhat.
Also i think I have another node of the opposite jawline. The problem is I can't really feel them. I really have to contort my head. I feel they are lymph nodes.
