Hi, I Have Had A Fever Now For Two +

Hi, I have had a fever now for two + days. No cough, no sore throat etc. only symptom is the fever plus some aches in joints. Temperature range has been 99.6 to 102.1. The lower end of the range is achieved after taking aspirin. My first inclination is to simply rest and ride it out but since it's ongoing I'm wondering if I should go in and get checked out by my physician or go to a nurse practitioner "doc in a box". Any thoughts?
