I am experiencing severe/ pain all over my body...neck, hands, arms, legs (trouble walking) feels like joint pain, EXTREME headache for 2-3 days, really sore throat. Last night had really bad chills, and threw up this morning. I had a infection in my finger, and was put on antibiotics, but I cant imagine it making me hurt all over like I am. I have been in bed most of day. My jaws hurt as well. I have been taking Advil but it doesn t seem to be helping.
