What is the outlook?In the majority of cases, tension headaches respond well to treatment. They are unpleasant but not usually harmful if they do not occur as a symptom of another condition.
For treatment to be effective it is important that the patient adheres to the doctor's instructions. Non-compliance or non-adherence is one of the most common reasons for treatment failures - not only for tension headaches.
When tension headaches occur as a symptom of another condition, they will generally get better when that underlying condition is treated successfully. If painkillers are used too often and for too long, there is a risk the patient may develop rebound headaches.
