Headache
Headache: Introduction
The possible causes of a headache range from a relatively harmless
common headache or common cold
to life-threatening emergencies like meningitis or even the unlikely
occurrence
of a brain tumor.
Various types of headache are possible: common headache, migraine,
cluster headache, sexual headache, or other types of headache.
Any incident of head injury (i.e. brain injury), even in the past,
raises the possibility of concussion or other results of head injury.
Headache also commonly occurs with various diseases that also cause fever,
of which there are numerous possibilities; see causes of fever.
Prompt medical attention for diagnosis and treatment is advisable
for any headache.
