A fever is a higher-than-normal body temperature, one of the body's natural responses to infection. A low-grade fever isn't usually a cause for concern, but a temperature 102°F and above should be treated.
Keeping this in view, when should you go to the ER with a fever?
Call your doctor if your temperature is 103 F (39.4 C) or higher. Seek immediate medical attention if any of these signs or symptoms accompanies a fever: Severe headache. Unusual skin rash, especially if the rash rapidly worsens.
Likewise, is it good to let a fever run its course?
It is not an illness in itself. In fact, a fever may do some good. A small but growing body of research shows that letting a fever run its course may reduce the length and severity of such illnesses as colds and flu. As for the concern among parents that fevers can have harmful effects, these instances are very rare.
How dangerous is a 103 fever?
For an adult, a fever may be uncomfortable, but usually isn't a cause for concern unless it reaches 103 F (39.4 C) or higher. For infants and toddlers, a slightly elevated temperature may indicate a serious infection.
Does a fever breaking mean you're getting better?
When the fever breaks, the thermostat gets set back to 98.6. That's when you start to sweat, throw off the covers, and hopefully begin to feel better.
