I all of a sudden last night developed a severe headache and my neck hurts when I move it around and my body and joints hurt to where I don't want to move because it hurts so bad I have a severe sore throat and it hurts to swallow or eat anything I don't feel eating anything I can eat popsicles though it kinda hurts a little and I'm freezing cold and my body is warm to the touch I don't know if I have a fever or not because I don't have a thermometer.
