Have you ever gone through a severe, blinding pain to a side of your face?
If yes, then you might be experiencing a neuropathic issue called Trigeminal Neuralgia. 
Usually, the pain affects only one side of the face at a time but can affect both sides in a rare case.
The pain attacks like an electric shock and can last up to two minutes, leaving the patient paranoid.
The traditional treatment often involves medication or surgery. But you can try some home remedies for Trigeminal Neuralgia pain before you rush to the doctors.
