I get this question a lot. Everyone who has ever had a fever or whose child has had a fever wants to know - how high is too high? When do we go from treating it at home to rushing to the hospital?
Fortunately, you almost never need to rush to the hospital due to a fever alone. Although fevers can be scary and make us feel pretty miserable, it is just a symptom of an illness, not an illness itself. The course of action you take really depends on all of your symptoms, not a number on a thermometer.
Most people who ask this question are concerned because they believe that a high fever can cause brain damage. Or at least they heard that at one time. I'm happy to report that there is no proof or evidence that fevers cause brain damage, regardless of how high they get.
So the next time you or someone you know gets a fever, try to relax. We have a lot of great resources to help you figure out what could be causing the fever and what you can do about it.
