3.3.2.2 Chronic SUNA

The patient, a 61-year-old retired bus driver, has had one-sided head pain for close to a year without a genuine break of more than about ten weeks. He notices the nostril on that side becomes blocked whenever an episode starts. The pain, moderate in strength, is felt around and in the eye and arrives as a cluster of quick, stabbing jabs rather than a single ache. He is certain his eye never turns red and never waters during these spells. Each episode lasts around three and a half minutes, and he now has roughly four a day; tallied over the whole year that comes to well over a thousand, something like fourteen hundred by his own reckoning.
