You may be suffering from a condition known as contact point headache. This type of headache is also known as:
• Sluder's neuralgia
• Anterior ethmoid neuralgia
• Sphenopalatine ganglion neuralgia
• Pterygopalatine ganglion neuralgia
This type of headache has often been confused with cluster headache, migraine without aura, sinusitis, or other undefinable pathology especially since CT scans and MRI scans that are obtained often do not reveal any tumor or presence of infection.
