"i have been on this medication now for 6 months for nerve pain and tingling down my leg from a trapped nerve in my back. 10 mg at night along with other paracetamol and ibuprofen certainly does relieve the pain. i was told to increase the nortriptyline as required to 20 mg at night if necessary but so far i have not had to do that. side effects have been virtually non existent against the benefit of it."
