Headache
A headache involves having mild to severe pain in a specific, or many, areas of the head or back of the neck. Countless “types” of headache exist, all caused by a variety of reasons, and although they can be painful and rather annoying, they are, for the most part, not a sign of a serious disorder and in most non-chronic situations can be treated and relieved by medicines.
Although there is no single cause of a headache, several causes have so far been identified by the medical community and these can fall into two main categories – tension headaches and migraine headaches. Tension headaches are the result of contraction of the neck and head muscles and are the most common type of headache, accounting for nearly seventy percent of cases. Some causes of muscle contraction linked with tension headaches include stress, fatigue, eye strain, poor posture, hormonal changes, and alcohol or tobacco use.
Migraine headaches occur when blood vessels located in the neck and head constrict, which therefore leads to decreased blood flow in them. Symptoms of migraine include a throbbing pain usually on one particular side of the head, along with a feeling of nausea and sensitivity to sound or light. Migraines are usually chronic and affect more women than men

Headache
Although for the most part headaches are not a sign of anything sinister, as mentioned above, there are certain symptoms that need to be looked at by a doctor or physician immediately. These include a sudden onset of headache accompanied by vomiting or nausea; recurring headaches which are accompanied by memory issues, tiredness and difficulty in concentrating; neck stiffness accompanied by high fever; fits; vision irregularities, i.e. light flashes; trouble controlling, or loss of feeling in, the limbs; and difficulty in communicating while being tired and apathetic.
