Hiyesterday I was having little fever and joint ache Special

Patient: Hi…yesterday I was having little fever and joint ache. Specially in the legs. And a little heaviness in the head. And I was not hungry the entire day. I was full all the time. I drunk plenty of water. Urine colour was normal. And I also took one calpol (paracetamol) but that did not help much.No runny nose, or swore throat or cough.Today m feeling a bit better. Less pain in the body.Should I be worried about swine flu. What should I do or which medicine should I take?

Doctor:
