HEADACHES

I had severe head ache for the past six months. While working on desktop computers I used to work without spectacles. My spectacles was designed for book reading and distant vision. In the course of time soon after working on computer without glasses I used to get severe pain in the head. I have got  spectacles suitable for working on computer.  It is giving good relief.

A head ache is pain anywhere in the head and neck. Brain itself is not the cause of head ache. There are no pain receptors in the brain. Pain is caused by disturbances in the pain sensitive areas around the brain.

Nine areas in the head and neck have pain sensitive structures. The thin coverage below skin called periosteum on the skull, muscles, nerves, arteries, veins, eyes, ears, and mucus membranes have all pain sensitive structures. 

Causes for head ache includes fatigue, sleep deprivation, tension, medication, viral infection, common cold, head injury, very cold beverages, dental and sinus issues.

AN AD TO PROMOTE HEADACHE MEDICIN

Head ache is harmless in most of the cases but in certain cases it may be life threatening. Neurological examination will decide the cause as serious or not. There are two types of head ache, primary and secondary. Primary head ache are benign and recurrent. They are not caused by any disease in the body. The primary headache may be coming daily but is not dangerous.

Migraines type of headache exhibits with pulsing pain, nausea, photophobia and phonophobia.  They are considered to be caused by dysfunction of nerves in the brain. Tension type headache is non-pulsing band like pressure applied on both sides of the head. They are caused by activation of peripheral nerves in the head.

Among secondary headaches, stiff neck, bleeding inside the brain, brain tumour, inflammatory disease of arteries, pain around any eye and increased pressure in eyeball are most common.

Most headaches are diagnosed by clinical history. If the symptoms described by the patient is found to be dangerous further testing should be conducted. If a patient tells that he has severe headache for the first time it calls for further tests such as neuroimaging.
