You have symptoms of the influenza virus. Get plenty of bed rest. Take pain relief medications as recommended on the packet that will also help to lower the fever.
Drink plenty of fluids, water and fruit juices so that you do not become dehydrated. Don't worry about not eating, as long you are drinking (keep off dairy products until you are well).
Unfortunately there is no cure for influenza, but if your symptoms do not subside over the next day or so, or you start to feel worse, get pains and start to cough, then phone your doctor for advice.
Wishing you a speedy recovery.
