Hi, I started experiencing body chills, headaches, sore throat and high fever (105) since Sunday Morning. My doctor did a swab test and test came back negative for Strep (which I thought I had). Now, exactly 24 hours, my ears are plugged, and throbbing, painful. Could this be a case of a very bad flu? And what can I take to resolve the pain? I am currently taking Advil Cold and Sinus 200mg, but this has stopped working and symptoms are getting worse.
