About 5 years ago after having a tooth removed I developed severe pain down the left side of my head. Doctors have been treating me for trigeminal neuralgia ever since, I have had so far gabapentin, amatriptaline, duloxatine, carbomezapine but to date none have worked and I still have severe pain the only thing that stops it for a short while is paracetamole but this does not last very long and the pain starts again. The pain wakes me every night at least once when I need paracetamole to stop the pain, has anyone got any suggestions to assist with pain relief except paracetamole
