6 Health Symptoms You Should Never Ignore

2. Persistent or High Fever

When you have a fever, it is an indication that your body is fighting against an infection, as it is supposed to. It is also recommended not to try to bring it down with medication, unless your fever runs very high (over 103 F), as it can hinder that process.

But, if you have returning fevers over an extended period of time and they are persistently high, that could be an indication that the infection your body is fighting is a much bigger problem than it can handle on its own. These could be conditions like tuberculosis, UTIs (urinary tract infection), or even some cancers like leukemia and lymphoma. Therefore, if you have a fever that persists at over 103 F (39.4 C) for more than 3 days, call your doctor!
