Hi, I had a viral thing about 3 weeks ago that included a diffused rash from neck down to mid-thigh, fever, headache, sore throat and extreme fatigue. A week ago the rash subsided, the fever only lasted about 24hrs and now I am still left with a headache and sore throat that begins in the early evening, come morning the headache and sore throat is gone.... I am stumped! Do you have any ideas?
