From my own experience, and reading about others' experiences, and literature on doses expected to provide relief, then if I understood you correctly, that you're currently on 3,000 mg per day, I don't think Neurontin is going to work for you. I have back pain and it went away overnight with your medicine's cousin Lyrica. If I misread what you wrote, and you're just on 300mg daily, you may need some increases, as you said the doc would do, until you DO get relief.
