3. Shaving
Shaving is another part of the self-care and grooming process which can cause trigeminal neuralgia to be triggered. The irritation of the skin during shaving is a highly exaggerated form of some of the lighter triggers, such as gentle touching, but a person can find themselves caught between a rock and a hard place when trying to avoid this trigger.
On the one hand, a person may decide not to shave because they know full well that the contact of the razor with the skin will trigger their trigeminal neuralgia, but on the other hand, a person who allows their facial hair to grow may find that the touch of the bristly facial hair on the skin provides another source of irritation.
Someone who has a particularly fast-growing beard can find themselves with a bit of a headache in this scenario, whether to shave regularly and keep irritating the skin or whether to allow the facial hair to grow and to try and deal with the irritation that this brings.
