Starting last night I quickly developed severe body aches, chills, exhaustion and have a fever of 101.2 F taken orally. I have taken a total of 6 advil liquigels and 2 regular strength tylenols in the past 24 hours. The fever will decend to 99.9 F at its lowest, and then will come back again a couple of hours later up to 101.2F. Everything hurts...but I have no cold symptoms (no runny nose, cough, or congestion). Could this still be the flu? Should I visit my family doctor for a prescription for Tamiflu? Or can you suggest another OTC medication?
