The most common type of headache is a tension headache and is the result of tight, clenched muscles. Overexerting your muscles or keeping your head in one position too long, sleeping on it in an uncomfortable position, or even grinding your teeth can result in a headache. These tend to occur on both sides of your head, not just one.
Other types of headaches can result from illnesses, including fevers. The serious conditions associated with headaches need immediate medical attention. The conditions include brain tumors, brain meningitis and strokes. Headaches associated with these conditions are much more rare.
Aside from tension headaches, the most common types of headaches are cluster headaches, sinus headaches and headaches associated with flu and fever.
Cluster headaches tend to happen many times each day over a period of months, are very painful and tend to disappear from one’s life as suddenly as they appeared.
