Expert writing Tips

Best practice

If you want to describe how the fever is affecting the person (e.g. causing discomfort or delirium), then use "suffering from a fever" or "experiencing a fever".

Common error

Be careful not to confuse "running a fever" with simply "feeling hot". While "feeling hot" can be a symptom, "running a fever" confirms an actual elevated body temperature.
