Advantages of lobbying 1) Society will be notified of important issues that may otherwise get swept under the rug or lost in the ordinary business of the day. 2) People are involved with the issues of their day and a variety of lobbyists keeps the sitting government on their toes.
Headache is a non-specific symptom, which means that it has many possible causes, including fatigue and sleep deprivation, stress, the effects of medications and recreational drugs, viral infections and common colds, head injury, rapid ingestion of a very cold food or beverage, dental or sinus issues, and many more.
However, headaches can occasionally be a sign of something more serious. Very severe high blood pressure (above 180/110 mm Hg), stroke, brain tumour, or an aneurysm (a dilated weakened blood vessel) in the brain may cause headaches. Meningitis (an infection of the brain's lining) may also cause a headache.
