Postherpetic Neuralgia
"I had many symptoms at first, especially imbalance, and drowsiness. I could never drive my car during the use of this medication. But overall, it helped with the sharp needle-like stabbing pain all over the area in which my shingles spread. I was worse case my doctor and neurologist had ever seen.  When the shingle scabs had fallen and my doctor said the episode was over, I had no pain. Then suddenly from nowhere terrific pain began to increase to the point where my doctor had to prescribe this medicine. I&#039;ve only been on this medicine since June. It is now September and dosage has only been increased once ( to 1800 mg per day)."
