A fever isn't necessarily a cause for alarm. Fever seems to play a key role in fighting infection. Persistent fever can signal a hidden infection, which could be anything from a urinary tract infection to tuberculosis. In some cases, cancerous (malignant) conditions such as lymphomas cause prolonged or persistent fevers, as can some medications...and many other causes are there...consult nearest physician for examination and few more investigations they will guide you further.
