There are many reasons a person may develop a headache but many don’t know that headache pills/pain medication is one of them. Regular, long-term use of headache pills can cause headaches. This is the so-called Rebound headaches.
Rebound headaches also known as ‘medication-overuse headaches’ are 
usually caused when a person with a headache problem like migraine use headache pills like Acetaminophen (Panadol or Tylenol with or without caffeine), Aspirin, Brufen and Advil regularly for a long time.
Headache pills are great for occasional headaches however if you use them regularly for more than a few days at a time you are at a risk of getting rebound headaches.
Rebound headaches might be difficult to distinguish from an original headache which makes the patient use more pain medication which in turn make the rebound headaches worse. It can be a very painful and frustrating experience.
A clue is that rebound headaches tend to disappear after taking headache pills and return just as the medication begins to wear off.
It is worth noting that research has shown that pain medication taken for other reasons apart from headaches is unlikely to cause rebound headaches.
How to Treat Rebound Headaches
The idea is to gradually reduce the amount of the pain medication you use. However, it is best to discuss this with your doctor so that he/she can rule out other causes of a headache that might look like a rebound headache but are far more dangerous and in some cases life-threatening.
