 Hello, I am Dr. Awdoomer Nethalkar. I am a consultant neurosurgeon and spine surgeon at Manipal Goa Hospital for last 10 years. And I just want to educate the general public about the entity called headache because headache is one of the commonest symptoms associated with a neurological disorder. Now, which headaches are significant and which are not to be taken very seriously? The prevalence of headache in India is around 62% of which migraine is about 32%. So it is that common. So it needs to be tackled very seriously. The commonest headache that we have is migraine headache, tension headache, cluster headache and sinus headache and other non-specific headaches. Now, as far as how to diagnose this, as far as the migraine headache is concerned, it is mostly one sided and it is throbbing or pulsatile and coming all of a sudden very severe in crescendo and resulting into vomiting at times and vomiting relieving the headache. Now, this vomiting is associated always with nausea. The tension headache comes as a band around your forehead or your back of the head or around the temples and it usually comes at the end of the day in the evening. Now, this tension headache is not secondary to tension. It is called so because there is a tension in the muscles of the head. The third headache is the cluster headache which is usually behind eye, very severe stabbing and with crescendo and descendo resulting into vomiting at times. And other non-specific are related to fever, any temperature that you have can give rise to headache. One more headache we should be aware of is the sinus headache which usually comes on the forehead or below the eyes associated with the redness of the eye or running nose. Now, coming to the headache associated with the brain tumor which people are always worried with 3-4 days headache, they will come to the doctor and say, I may have a brain tumor. It's not like that. Usually a headache which is around 5-10 days old, you must consult a neurospecialist. And the brain tumor headache usually comes early morning. It wakes you up from sleep and this is dull. It's not very severe. And then it is associated with the vomiting which is projectile. Projectile vomiting is something which is not preceded by nausea. It just comes up suddenly because of the raise of the pressure of the brain leading to vagus nerve stimulation and vomiting. And this vomiting usually relieves the headache. So, if this headache more so it is associated with a blurred vision or a double vision, you must always consult a neurospecialist. Because double vision, blurred vision headaches are 90% associated with the brain tumor and can take a serious turn if they are not attended to. Also, any headache associated with the paralysis of the hand or leg on one side or numbness of the hands or legs or any associated symptoms like unconsciousness, epilepsy, you must immediately consult a neurospecialist. Everything will be okay if you consult the doctor as early as possible.
