In thinking back over my illness, I don't recall ever having swollen lymph nodes. But I could just be forgetting having them.
Sun reactions do tend to cause headaches, body aches, and general feeling of flu or malaise. It can take up to 10 days after being exposed to the sun or florescent lights for my body to get back to normal, you probably have the same kind of time frame in store.
Get plenty of rest, drink lots of water - and if it lasts more than 7-10 days, then think about
seeing a Dr. That's what I'd do, anyhow.
