Swollen glands in my throat, my chest feels tight/tired, a cough and a constant bad headache and a fever (sweating/burning to freezing/shivering)?

Influenza. is very common viral infection. Usually the condition resolves on its own with home care. Antibiotics do not help. Drink water and get a good rest. NSAIDs (e.g. Aleve, Advil) or Tylenol (acetaminophen) are also recommended every 6 hours. If concerned, see your PCP for examination.
Sounds viral. Could also be mono. See your doctor and have a simple titer drawn.
