Although medical science has not yet found the exact cause of headaches, some of the most common causes can typically be blamed in the majority of cases. Headaches are broken down into three basic categories. A primary headache occurs to millions on a daily basis. Primary headaches constitute the vast majority of headaches, and are almost never life threatening. Despite this frequency of occurence and a lack of life threatening danger, a primary headache can be very painful. Cluster headaches are a far more serious form of headache, that although not life threatening, can bring about serious pain. Secondary headaches are sometimes a sign of a deeper neurological issue.
It is believed that over 90% of primary headaches, which most people experience, can be blamed on tension. The muscles that surround the skull sometimes contract, putting too much pressure on the head. This can be a significant source of pain. Although the reasons behind the contraction of cranial muscles are unknown, it is commonly seen as a result of emotional or physical stress. Significant emotional stress usually leads to cranial pressure, and therefore a tension related headache. Prolonged physical stress, such as extended manual labor, is also known to cause tension headaches.
Cluster headaches are a far rare occurence, and usually only afflict a tiny segment of the population. Patients typically see cluster headaches only in small time frames, thus the name “cluster” headache. This can make prevention and treatment difficult. When a cluster headache occurs, severe and debilitating pain usually follows. Water running from the eyes and nose are common with cluster headaches. A cluster headache should be treated as soon as possible.
Secondary headaches occur as a symptom of a more serious problem. This is much rarer than primary headaches. A secondary headache can be indicative of internal bleeding in the brain, a tumor, or a malfunction of the brain. Headaches that occur on a chronic basis should be cause for a check with the doctor. Secondary headaches sometimes present with severe pain and sensory issues.
