question: A dentist and Doctor at work believe that I am suffering from Trigeminal Neuralgia. I went to my GP in the hope that he would refer me but he has asked me to take Dihydrocodeine twice a day and go back to him in a weeks time. I am confused because my last 'epidsode' was six months ago and I really don't want to take strong painkillers unnecessarily. Is there a reason behind his thinking?
