The most painful nerve to damage is the trigeminal nerve.
Damage to the trigeminal nerve leads to a condition called trigeminal neuralgia which is also known as tic douloureux.
Trigeminal Neuralgia is a chronic pain condition that causes sudden, intense and sharp or stabbing pain in your face.
Trigeminal Neuralgia affects your trigeminal nerve which is the nerve that carries sensations from your face to your brain.
The pain can feel like an electric shock or a joint and can be triggered by seemingly innocuous actions such as washing your face or even brushing your teeth.
Trigeminal Neuralgia is often caused by a blood vessel that presses on your trigeminal nerve and can damage your nerve's protective coating also known as myelin sheath.
And other causes of Trigeminal Neuralgia include tumors, multiple sclerosis and even other nerve damage.
The symptoms of Trigeminal Neuralgia are a sudden and intense, sharp or stabbing pain in your face.
As well as pain which feels like a jolt or electric shock and pain which can be triggered by seemingly innocuous actions and pain which can occur in bursts or clusters.
Treatment for Trigeminal Neuralgia are medications like anticonvulsants which are often used to manage the pain and surgery in some cases may be required to relieve the pressure on the nerve.
