Step-by-step explanation:
Rebound headaches, also known as medication-overuse headaches, are headaches that occur daily or nearly daily and are often caused by the overuse of headache medication. This type of headache is a common issue where the very treatment for a headache can lead to the development of a new headache once the medication wears off. Treatment for rebound headaches typically involves reducing or stopping medication that has been overused, and sometimes using preventive medications and behavioral therapy.
