Re: Swollen lymph nodes that won't go away...
Did they test you for Epstein-Barr Virus? I was having swollen lymph nodes and my doctor checked and saw that I'd been positive for EBV on previous bloodwork (which he'd never told me about! Although I read later than most people test positive for it because it's a very common thing but most people don't know they have it because it stays dormant their whole lives). But I had the same symptoms as you that went along with the swollen lymph nodes- feeling tired all the time, fatigued, headaches... He advised me to take Vitamin B supplements, which usually help when I get a flare-up of the virus.
