I have had a fever as high as 103.5 for 5 days, my body aches, chills, headaches, I have no appetite, shortness of breath, my ribs feel bruised, I have no energy. My period is almost 2 months late(all tests for pregnancy negative), I have an IUD. My doctor told me I have a virus but did not prescribe any medication. I'm miserable sleeping, working, even sitting. What do I do!?
