This is a severe type of headache of a recurrent nature and typically causes pain on one side of the head, especially around the eye. The associated symptoms include watering from the eyes, swelling around the eyes and nasal congestion, occurring on the side of the pain.Tension Headache
This type of headache accounts for almost 90% of all headaches and is felt as a sense of constant pressure on the head. The pain may also radiate to the eyes, neck and upper back. Any physical or emotional stress like irregular food habits, inadequate sleep or emotional turmoil can bring on this headache.Brain Aneurysm
This disease is characterized by ballooning of an artery in the brain because of weakness in the artery wall. Depending on the location of the aneurysm, symptoms can be seen such as headache, dizziness, blurring of vision and sense of numbness. A fatal complication of the disease is when the aneurysm bursts causing blood to leak into the brain and cause haemorrhage.Temporal Arteritis
Inflammation and damage to the temporal artery (one of the arteries supplying blood to the brain) is called temporal arteritis. The cause is unknown though it has been seen to pass among generations of families. Apart from the throbbing nature of headache, patients experience sensitivity on touching the scalp, excess sweating, neck stiffness, jaw pain and fever.Ethmoid Sinusitis
Inflammation and infection of the ethmoid sinuses (situated near the bridge of the nose) is called ethmoid sinusitis. Headache begins on one side, akin to migraine, and then progresses to the other side. Along with this, sneezing and nasal discharge are also present.
