I’m not sure if it’s neuralgia that I’ve had but about 2-3 occasions where I’ve had stabbing pains like a knife stabbing me, in different areas of head, latest being over the small bone around my ears.
It lasted about a week each time, and one occasion went to out of hours surgery over a bank holiday. Was prescribed Zapain, it certainly helped but was on these for about a week from start of pain to finish. Since this incident I’ve been told zapain is usually recommended for something else like bone pain, But it did help me. I was finally able to sleep, these tablets are very very strong for 2 days couldn’t do much else. Good luck in finding the suitable one
