"when i was 47 i was diagnosed with arthritis in my neck which was triggering migraines and shoulder pain. even 800 mg of motrin didn&#039;t help. nortriptyline was a miracle and i am migraine free. i tried going off of it about 4 times, and every time i had headaches and shoulder pain the next day. i am so thankful for nortriptyline because i can go to work and think clearly without a headache clouding my thoughts."
