Headaches are one of the most common illnesses in Australia, with around 15 per cent of us taking painkillers for a headache at any given time. Because headaches are so common, most people think they are a normal part of life. However, a persistent headache is a sign that something is wrong. The continual use of pain medication to combat headaches is akin to removing the warning light that alerts you to a problem in your car! Medication doesn’t solve your headache, it simply offers a short term solution to dull the pain.
