Cough headache presenting as a toothache: a case report.

Benign cough headache (BCH) presents as an intermittent, usually bilateral, severe bursting or explosive pain brought on by coughing. Some of the known conditions which can mimic the pain experienced in BCH are subarachnoid hemorrhage, increased intracranial pressure, intracranial tumors, and even toothache. Careful evaluation must be carried out in order to differentiate between these conditions. A case of BCH which presented as a toothache is reported. The evaluation for exertional headaches, and for headaches brought on by coughing, is discussed.
