Unexplained fever: Fever rarely lasts longer than a month, and this (if you've measured it accurately) puts you in the category of fever of unknown origin, which is mostly due to chronic diseases. Some considerations include: chronic infection (eg cmv, toxoplasmosis, mono), autoimmune disorders like lupus or vasculitis, cancer, leukemia, and very rare infections like histoplasmosis, coccidioidomycosis, q fever, etc.
