Hi everyone, would really appreciate anyone’s help and advice on this. My Dr thinks I have Trigeminal Neuralgia and he’s started me on carbamazepine yesterday was just wondering how long it takes to work and your experiences of it. I’m reduced to tears with the pain this morning and it’s awful been getting steadily worse over the last week. I had the same on the left side 3/4 years ago and had a feeling then that it was TN but it’s now on the right side and so much worse, it’s hell on earth at the moment. Guess I just want to see some light at the end of the tunnel.
