Nortriptyline
vulvodynia
"Started at 10mg & pain lessened overnight! After few weeks, stepped up to 20mg, more improvement. In last few days upped to 30mg & I am almost discomfort free. This is after suffering on & off for some years. Plus my recurrent migraines  have stopped. And pain from both knee osteoarthritis & wry neck very improved. So, yes, this medicine worked for me. Side effects were transient & tolerable."
