Hi, I ve been running a fever of 100-104 since Wednesday night...I feel a little better during the days, but nights are really bad....shaking for hours. I ve been alternating taking Advil and Tylenol every 4 hours since Wed night, but I feel like I m not responding as well anymore....I just took 600mg of Advil an hour ago and my fever is still over 100. There is no urgent care clinic in the small town I m in, so my only option is the ER....I m wondering if this warrants a trip to the ER at this point? I m also coughing, have congestion but no vomiting.
