I want to welcome you to Neruo Talk. You are doing very good by your mother to find out all you can about her nerve pain. Gabapentin or neurontin, is for nerve pain. Maybe you could go with her and ask if this medication can be increased. 300mg is a low dose. Other medications can also help. Keep a pain journal. Doctors appreciate this kind of attention to detail. Times, duration, intensity, and what so far has worked for her. Keep doing the research as you have been. Has your mother had an MRI for her back to rule out anthing in the spine causing this pain? I am sorry your mom and your family is going through this. No matter where we live on the planet, it is not easy to deal with pain. Welcome again, and post all the questions you want to the forum. ginnie
