7 signs and symptoms not to ignore

2. Persistent or high fever

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.

Call your doctor if your temperature is 103 F (39.4 C) or higher or you've had a fever for more than three days.
