My sister in law has nerve pain and she takes a combination of drugs such as a small amount of Lyrica , a small
amount of an antidepressant, a small
amount of lamictal and so forth. Be open to whatever the right combination is for you. I find amitriptilyne helps my back pain even though it is an antidepressant and I'm actually using it for migraine treatment. Also, some drugs have to be at a higher dose to work while others can work in small doses and work together well with others..
