The 7th Annual "Light Up Teal" event takes place in Waterford tonight to highlight the condition of Trigeminal Neuralgia.
It’s an excruciating nerve pain which affects the head and face and has been compared to being stabbed or struck by lightning.
There’s currently no cure and sufferers are calling for the condition to be added to the World Health Organisation’s health topic list to create opportunities for funding and research.
The Tower Hotel in Waterford have agreed to light up the bottom windows of the hotel in teal and people are asked to attend at 7.45 pm for a photo on the steps of the hotel.
The event in Waterford will join over 300 building's worldwide in "Lighting Up Teal".
The chronic condition is very rare and affects over 1,000 sufferer's in Ireland.
