Tension-type headaches can be either episodic or chronic. Episodic attacks are usually a few hours in duration, but it can last for several days. Chronic headaches occur for 15 or more days a month for a period of at least 3 months.
Migraines -A migraine headache may cause a pulsating, throbbing pain usually only on one side of the head. The aching may be accompanied by:
Sensory disturbances known as auras
Migraine is the second most common form of primary headache and can have a significant impact on the life of an individual. According to the WHO, migraine is the sixth highest cause of days lost due to disability worldwide. A migraine can last from a few hours to between 2 and 3 days.
Rebound headaches - Rebound or medication-overuse headaches stem from an excessive use of medication to treat headache symptoms. They are the most common cause of secondary headaches. They usually begin early in the day and persist throughout the day. They may improve with pain medication, but worsen when its effects wear off.
Along with the headache itself, rebound headaches can cause:
A feeling of nasal congestion
Reduced sleep quality
Rebound headaches can cause a range of symptoms, and the pain can be different each day.
Cluster headaches usually last between 15 minutes and 3 hours, and they occur suddenly once per day up to eight times per day for a period of weeks to months. In between clusters, there may be no headache symptoms, and this headache-free period can last months to years.
The pain caused by cluster headaches is:
Severe often described as sharp or burning
Typically located in or around one eye
The affected area may become red and swollen, the eyelid may droop, and the nasal passage on the affected side may become stuffy and runny.
These are sudden, severe headaches that are often described as the “worst headache of my life.” They reach maximum intensity in less than one minute and last longer than 5 minutes.
A thunderclap headache is often secondary to life-threatening conditions, such as intracerebral hemorhage, cerebral venous thrombosis, ruptured or unruptured aneurysms, reversible cerebral vasoconstriction syndrome (RVS), meningitis, and pituitary apoplexy.
People who experience these sudden, severe headaches should seek medical evaluation immediately.
