Have a constant headache, low grade fever & swollen feet for 3 weeks. ct scan of head and cbc normal. no relief with prednisone or pain meds. help?

Headache: This is a common complaint and can result from many underlying illnesses. You have a fever of undetermined origin, and without knowing what evaluations have been done and the rest of the medical history and exam my best suggestion would be to see an infectious diseases expert. Do not know why you were given prednisone, but this does not, superficially, sound like a good idea. See an id doc.
