text: The classical symptoms of meningitis are headache, neck stiffness and photophobia (intolerance of bright light); the trio is called meningism. Fever and chills are often present, along with myalgia. An altered state of consciousness or other neurological deficits may be present depending on the severity of the disease. In meningococcal meningitis or septicaemia, a petechial rash may appear. A lumbar puncture to obtain cerebrospinal fluid (CSF) is usually indicated to determine the cause and direct appropriate treatment.\n\nConvulsions and hydrocephalus are known complications of meningitis. If symptoms occur see a doctor urgently as treatment needs to occur early to be effective.
