Every few months I get a single 24 hour day of strong body aches, strong aches in my joints (particularly my fingers and toes), strong muscle aches In the back, chills, sweat, fever, really dizzy, headache, essentially strong flu-like symptoms, then the next day it is gone. I may feel a little week the next day, but no aches or fever. During the episode I am bed ridden and worthless. No appetite, but no nausea either. It seems to happen once every 3 to 4 months.
