2. Apply Pressure
Probably the first thing that anyone would learn on first aid or a first responder course is to apply pressure. It can be used to solve pretty much any situation you might be faced with, and the pain from trigeminal neuralgia is no different.
The amount of pressure that will give pain relief varies massively from person to person, and all comes down to the sensitivity of their skin and their pain threshold. Some people find that light touch can provide relief from the pain symptoms, whilst others claim that even a soft breeze or a delicate brush can actually trigger the pain.
Interestingly, a lot of people who claim that light touches trigger their pain find that harder application of pressure can actually serve to give some pain relief. The best way to apply pressure is with the hand and usually, a fully opened palm across the affected area is the best plan of action to give adequate relief.
