Being extremely tired, having a stiff neck, a mild sore throat, slight swollen glands, and headache, are symptoms of what?
I know you asked this a long time ago, and I wonder if you have a diagnosis and treatment you would like to share?
We are not doctors here, and your symptoms could indicate anything from a cold to fibromyalgia to meningitis to allergies to a virus. Your doctor is the only one who can diagnose and differentiate.
I do hope you are well! If you would like to read up on some of these symptoms, I have a few links:

I don't know, but I have it too. I notice you were sick on 16th March. You better now? :)
