Please SHARE this on Facebook and help others become aware of these hidden dangers.

1. A sudden, severe headache

These are called  “thunderclap” headaches and they usually peak in intensity within 60 seconds. The pain may improve after an hour however they can be very dangerous. They are often caused by bleeding in the brain that can occur after an aneurysm, stroke or other injury.  Other symptoms associated with these headaches are nausea, vomiting and mental confusion.


2. A Headache after a head injury

A headache that follows a head trauma can indicate a brain injury such as a concussion or haemorrhage. In some cases the headache starts days after the injury. It is especially concerning if the headache continues to worsen after the injury.

Remember even a minor fall or bump to the head can result in potentially life-threatening bleeding (haemorrhage) in the brain. Other symptoms of brain injury can include loss of consciousness, vomiting and weakness, memory loss, impaired vision and changed mental state.

3. A severe headache with a fever and stiff neck

This type of headache can be due to meningitis, an inflammation of the membranes covering the brain and spinal cord. This is caused by a viral or bacterial infection.

Other symptoms of meningitis are fever, rash, light sensitivity and muscle rigidity. This condition is life-threatening and needs immediate medical attention.

4. A headache with one-sided numbness and weakness

A sudden, severe headache with weakness and numbness on one side of the head and down to the shoulders
and arms can indicate damage to the venous sinuses in your brain. If they become clogged they can cause bleeding in the brain and a stroke. Other symptoms to beware of are speech and vision impairment and also sensitivity to light and loud noise.

5. A headache with neck and face pain

A tear in one of the carotid arteries that supply blood to your neck, face, ears and head can cause these types of headaches. This called a carotid artery dissection (CAD) and will lead to a stroke. They are usually experienced as a sudden and intense headache.

6. A headache after physical exertion

A headache that occurs after heavy exertion and is felt as a sudden severe pain, could be indicative of a haemorrhage, stroke or tumour and needs to be investigated. Other symptoms to be concerned about with exertion headaches are speech, balance or vision changes

7. A new or unusual headache
