Likely a Mild Case:: You are correct. Influenza often comes with a fever & body aches. However, that isn't always the case. The most consistent flu symptoms are what you described, the respiratory symptoms of cough, sinus issues, & sore throat. How severe your symptoms are can also depend on the strain of flu, & the strain of flu can very from season to season. Once you've recovered, you can still get your flu shot!

Mild case: Although fever is usual for flu, at the beginning it is possible to not have fever.We don’t always test everyone without fever,so there may be more people diagnosed with a cold or other virus who would be positive for flu.Most important either way to rest,drink fluids,and call your doctor back if you are worsening,especially if you develop difficulty breathing,and you still may develop a fever.

Mild case: There is a spectrum of flu cases, serologically proven, that goes from no symptoms to mild symptoms to severe symptoms. It is likely that you had a mild case.
