October has finally arrived, which means that the 4th International Trigeminal Neuralgia Awareness Day is almost upon us. On October 7th the Light Up Teal campaign will see buildings across the world light up in a teal hue, with many buildings in Ireland joining the awareness campaign. So far, confirmation of 34 structures has been received, including the 3 Arena, Convention Center, Mansion House, Cork City Council, National Concert Hall, Christ Church Cathedral, Shannon Airport, NUI Maynooth and Galway Cathedral. Elsewhere, Niagara Falls, the Canada Peace Bridge, Perth Concert Hall, the Trafalgar Sq Fountains, Taipei Tower and The Sichuan Tower to name just a few, will don the same colour also.
