When Should You Worry?

As a doctor, I commonly get asked about headaches. At the back of my mind, I am always searching for clues that might lead to the nastier causes for a headache such as brain tumours and bleeds on the brain. Things I look out for are:

  • Headaches that are different from normal for that person.
  • Early morning headaches.
  • Any associated visual disturbances like blurred or double vision.
  • Odd sensations in the arms or legs, hands or feet.
  • Any recent head injuries.
  • Sudden onset of a severe headache.

Do I Need a Brain Scan?

Not everyone who has a headache needs a brain scan, and we should avoid exposing ourselves to unnecessary radiation. Doctors need to work out who would most benefit from a scan, and that’s not always easy. If you are suffering from any of the above symptoms then it may be recommended that you have a scan.

Migraines affect 8.5 million people in the UK. Identifying and avoiding the things that trigger migraines is an important part of managing them, says Dr Dawn Harper.
