I don't have fever but my entire body is aching and i have a headache and a sore throat with a slighty runny nose. whats wrong with me?

Flu-like illness: Sounds like you have a virus, possibly the flu. Stay hydrated, stick with clear liquids if you get nauseated, and take Ibuprofen for the achiness.

Likely viral: You probably have a viral syndrome with possible influenza or just a cold. Is good to show your throat to a dr to rule out streptococcal infection or other pathology. If you have neck rigidity or stiff neck is imperative to see a dr right away.
