Hi, i have had headaches for over a week now, two swollen lymph nodes in my neck, stiff neck and tiredness. no fever any ideas?

Sounds like a virus.: Sounds like a viral illness, which can last 1-2 weeks. Drink plenty of water, eat a healthy died, get lots of rest and take it easy. If you don't feel better in another week of taking good care of yourself, then see a doctor.

Viral infection: The cluster of symptoms point to a viral infection, such as the now ever present flu. You may have a low grade fever or it may be coming. If does not abate, see md, fluids, rest. Best of luck!
