Sounds like anxiety symptoms from worrying about your lymph nodes. You got yourself in a constant state of panic and the symptoms are coming out. I don't know anything about lymph nodes, but I've read so many posts on here about them and some say to see if they get bigger, some have gone to doctors and they doctor wasn't concerned. And I also know that even allergies can enlarge a lymph node. All you have to do to stop worrying is go have a doctor feel them - then presto, you'll be fine, your anxiety symptoms will leave and you'll be good as new.
