Tension (muscle contraction) headache


DIAGNOSIS


1 This is a ‘featureless headache’ with none of the above associated symptoms
as for migraine, and that lacks a family history or trigger factors other than
stress, or some craniocervical musculoskeletal problems.
2 Women are more commonly affected and the pain comes on gradually, is
bilateral, mild to moderate, dull, constant and band-like.
3 Mild nausea, phonophobia and photophobia can occur, but are usually
absent and vomiting is rare. Headaches often become chronic.

MANAGEMENT

1 Give the patient an analgesic such as paracetamol 500 mg and codeine
phosphate 8 mg two tablets orally 6-hourly.
2 Reassure the patient and discharge back to the care of the GP.

Post-traumatic headache


DIAGNOSIS


1 Headache following head injury may begin immediately or after a few days,
and is present in up to 30% of patients at 6 weeks after mild concussion.
2 Inability to concentrate, irritability, dizziness, insomnia and even depres-
sion may develop, known as the ‘post-concussion syndrome’.
3 Request an urgent CT head scan if there is persistent worsening of headache,
recurrent vomiting, clouding of consciousness, or focal neurological signs,
to exclude a subdural haematoma.

MANAGEMENT

complete recovery is the rule.
2 Refer the patient back to the GP, as symptoms may persist for up to 1 year.
