Expert writing Tips
Best practice
When describing medical conditions, use "acute onset" to clearly indicate a sudden and severe start of symptoms. This helps differentiate from chronic or gradual conditions.
Common error
Do not use "acute onset" to describe the severity of a condition itself, but rather to specify the suddenness of its beginning. For example, say "acute onset of severe pain" instead of "acute onset pain" if you want to convey both the sudden start and the intensity.
