I have had a chronic tension headache for just over 3 months now (everyday all day) I was finally prescribed 25 mg of nortriptyline by my neurologist. I have always had a minor case of anxiety but as the months gone by its slowly gotten worse. I'm going on my 10th pill tonight and I feel like my headache has gotten worse and my anxiety is much higher. Muscle tension in my shoulders and neck is now extremely uncomfortable and worse than before. Is this normal while on nortriptyline before it takes affect? Has anyone else used nortriptyline for chronic tension headaches specifically. Should i just tough it out and see what happens?Any advice is much appreciated.
