For The Last 4 Days I Have Been Feeling Very

for the last 4 days i have been feeling very weak.i have mild body aches and low grade fever at times. a couple nights i wake up sweating. my skin is also mildly itchy. I doesnt seem to be getting better yet. A couple weeks ago i had a sinus infection and couldnt hear well. My symptoms point to flu or drug alergy. i have not changed any meds in 5 months.
